Translate components of method dispatch to Python argument names?

[HalfWhitt]

What is the problem or limitation you are having?

Objective C methods names can end up being really long, for example this calling of NSCosntraint's init:

self.native.addConstraint(
    NSLayoutConstraint.constraintWithItem_attribute_relatedBy_toItem_attribute_multiplier_constant_(
        self.native,
        NSLayoutAttributeTop,
        NSLayoutRelationEqual,
        self.native_stepper,
        NSLayoutAttributeTop,
        1.0,
        0,
    )
)

Describe the solution you'd like

My quite possibly naïve impression is that this would be much more legible if it were possible to call it like:

self.native.addConstraint(
    NSLayoutConstraint.constraintWith(
        item=self.native,
        attribute=NSLayoutAttributeTop,
        relatedBy=NSLayoutRelationEqual,
        toItem=self.native_stepper,
        attribute=NSLayoutAttributeTop,
        multiplier=1.0,
        constant=0,
    )
)

...Perhaps even accept snake_case too, if that wouldn't be a bridge too far (pun intended).

I would usually prefer to come up with at least a proof of concept to propose, but considering how unfamiliar I am with Rubicon and Objective C generally, I wanted to check first if this would even be desirable (and seem possible) in the first place before going down any rabbit holes.

Describe alternatives you've considered

A handful of # noqa in beeware/toga#2993 and some uncomfortably long lines aren't the end of the world.

Additional context

Just noticed this while looking at the aforementioned PR.

Wow. I had even seen #148 mentioned on beeware/toga#2975, but not clicked through and realized the full context. Please ignore.
