You can have arguments with default values, which are optional, and the
last argument can be a list, as explained in the help:

Variable arguments are defined as the last argument, with a name
and have a list type, similar to TypeScript. For example, a
list of numbers: >
def MyFunc(...itemlist: list<number>)
for item in itemlist

Of course you can. But you can't access the arguments with the "a:"
dictionary or the a:000 list. Not only was this inefficient, it was
also rather weird. I don't think this will be missed.
