If we all get convinced that named parameters are worth it,
I think this is not going to happen because some people (two?) don't
want this feature.
I think they worth it and it is the right time to talk extensively why
people think they don't.
And reasoning should not be about its failure or success in another
language, we better have our own rules.
IMO named arguments in D at least should do:
- Reordering (since we got default parameters, even better)
- It is enabled only if we have access to the function declaration.
- In a function call we either use named arguments for all the
non-default arguments or call it with the usual syntax. No hybrid stuff,
no confusion.
A different rule can be:
- Named arguments come last.
- Any previous arguments match the order.
IMO the main that makes NAs confusing is allowing hybrid calls.
I don't think allowing reordering then introducing two new rules on
ordering is a good idea.
