We can and will eventually improve this by allowing compound names and with some extra sugar on top it will become what you want, at least from the call side, this won‘t add argument labels even if it seems that it should because you have parameter labels which are faked.

Extending declaration names for closures

SE-0111 was accepted with a small temporary regression of loosing parameter labels in closures. In an extra commentary to this regression the core team pitched a solution that would be purely additive to the language without being a burden for the type system like pre SE-0111. The solution has to come in two steps: We have to extend the declaration names to allow labels in parentheses for variables, properties and parameters. (The following code snippet does not use , in between labels becau…
