Pretty cool especially since it avoids the problem when refactoring code
of knowing whether the use of the default param was intentional or just
as a filler to reach a later parameter.
I do have two remarks though:
- I hope it doesn't mean giving up on named args, because that would
look way cleaner.
- Would it be possible to allow trailing commas in combination to this?
i.e. foo("arg",) would just call foo with "arg" and then the default
value for the second arg if there is one, or just nothing. That would
make multi-line function calls a bit cleaner, and more similar to arrays.
