Godot: Wildcards in function arguments

[bojidar-bg]

Given that we now have TK_WILDCARD in GDScript, and _ is officially banned as a variable ( @karroffel ), I would like to request to be able to write this:

func handler(_, _):
  pass # Might actually complete this function one day

Instead of:

func handler(discard = null, discard2 = null):
  pass # Might actually complete this function one day

[karroffel]

It's not merged yet btw.. 😄

[bojidar-bg]

@karroffel My bad -- anyway, I guess it would be merged given the community response on that other issue...

[karroffel]

I still need reduz consent 😄

The PR #7583 has been merged by Akien a day ago. So this is a valid issue now.

I'm for pythonic

func handler(*args):
  pass

or even

func handler(*_):
    pass
````
in case of wildcard.

Python btw pack `*args` in this way:
```python
def a(*args, **kwargs):
    print args, kwargs # [1,2] {'x':3, 'y':4}
a(1,2,x=3,y=4)

I prefer pythonic if we need to add this feature too

I'm not speaking about varagrs, I'm speaking about using _ as a parameter name, to make an ignored value. i.e. for stuff like func do_stuff(_, second_param) over func do_stuff(something_not_going_to_be_used, second_param)

[karroffel]

I think it's worth adding. It's making use of the new token and if (ever 😢) the lambda PR gets merged then this

var f = func(x,_): x

looks a lot sexier than

var f = func(x, y): x

because it's clear from the argument list that only the first param will be used.

I might take a look at how easy it is to implement that.
