Pre-RFC: Named arguments

[scottmcm]

@Ichoran

Both of these are incredibly boilerplatey at both the definition site and the use site. So this is a good argument for named arguments. (Or improvements to boilerplate.)

I think the parenthetical might be the key, here.

"Rust doesn't have named arguments" isn't the problem. Rust doesn't have lots of things.

So the best way to make this move forward might be to make progress on something that helps similar intent to named arguments, but without having such pervasive effects as exactly named arguments.

For example, there are steps that could make builder-lite APIs easier, and thus more likely to be used. Perhaps things like ekuber's RFC in Pre-pre-RFC: syntactic sugar for `Default::default()` - #75 by ekuber
