[swift-evolution] [Idea] Omit argument labels from the call site when the argument is the same as the label

[Kenny Leung]

Hi Tino.

I think my idea is significantly different from yours. Making all labels optional feels more like a “reversion” of coding style to languages that don’t have argument labels. It would still let you call a function like this:

    you.doYourThingWithThis(a, b, c, d, e)

thus making your code harder to read.

I think making them optional only when the variable name is the same as the label does not take away from the reader understanding exactly which method is being referred to.
