if f is a function, then the second notation implies the function has at least an argument, while in the first one it has none. this is not coherent

nope, these two don't do the same thing in powershell.
a.f() would look inside the object and find the 'key' f and it's data.
But since a doesn't have a $, it will just error out.
f(a) would work.

They represent method call vs free function call. In many languages:

>f(a) means f is a standalone function taking a as an argument.

The caption jokes about developers preferring the method-call syntax (a.f()) because it triggers IDE autocompletion (you type a. and get a list of methods). With plain function calls (f(a)), you don’t always get context-sensitive autocompletion, so developers feel like they need the dot syntax even if both ways are logically the same.

So the "one character per function call" is the extra . you add to make autocompletion work.

noun.verb implies that for a verb to exist it must have a noun that "has" the function as an action it can perform. so now if you simply want to have a function to something you need to attach it to some pre-existing noun or make one from scratch, with all the design complications that come from that

So a is a structure that hold a pointer to a function f?

there is a difference between a.f() meaning that f() is a function inside namespace a, and f() being an action that the "object" a can perform. This is why the :: notation was created for OOP

>>106482732
a.f() is more convenient because 'f' is scoped in the class of a, so 'f' can be a nice short name, whereas in f(a) f needs all the usual namespacing and lengthening to avoid collisions.

Besides, there's no language that ONLY has method syntax, that wouldn't even make sense. Everyone is free to use the way that's more natural to them, so I don't know why anyone would be seething about this. I guess that's how it is if your job is to ragebait webshitters on twitter.
>>106483479
This is also a good point. In Rust a mutating function actually needs f(&mut a), while with the method would still be a.f(). But that's a mostly self inflicted problem, I guess.

The first one takes a as implicit argument you niggers

.f() implies the function is a member of an object, f() implies that it is a regular function. they are not the same. you could in theory call f(b) and not b.f(), assuming b does not share any inheritance with a.

>>106485766
>.f() implies the function is a member of an object
depending on the language. Same syntax can have different meanings in different languages

no it doesn't unless you're talking about a specific language
but in another language f may or may not be a method of a and only use virtual dispatch if a is an indeed object and f is indeed a virtual member

that is the syntax in all oop languages. there are maybe some meme langs i am unaware of, but the example was

>>106485736

>>106482732
my compiler does both because #1 is just syntactic sugar in the parser

because sometimes you need more parameters you absolute retard

b.f(a)

is what you want, because a rarely has enough context, and

means passing an ever growing context through your system, which sucks. let your framework construct b out of the pieces it needs and you'll get individually testable units for free

It's not object oriented slop. In a non-OOP language `a.f()` is just sugar syntax for `f(a)`. Only in OOP does it start to involve virtual tables and more leg work, ultimately doing the same as `f(a)` just a lot more hidden behind the scenes to handle calls to the superclass (if needed)

>>106487795
The dot notation is not necessarily an OOP concept, though.
It could just be an associated function of a type.

>>106482732
First one is namespaced.
If you go with the second option you'll have to do
fA(a), fB(b), etc as more structs use f function.
Also fuck whoever uses a single character for their functions. A dot is 50% of the characters when your function is a single character but normally they are at least 4, so more like 20%, less of a deal

>>106482732
The benefit of method call syntax is that the function doesn't have to be in the root namespace. If you want to use traditional function call syntax, you either have to fully qualify the namespace of the function, or import the function into the root namespace. So it actually looks more like:

T.f(a)

or

import f from T
f(a)

>>106487682
(F a b) can be a method specialised on both a & b instead of a method specialised on a alone in a.f()

>>106486082
But the actual difference is a(f) will jump to where a is.
a.f() will have to go to function call table of a and find f then jump there.
