Easy: allow an empty list to have the same meaning as an empty tuple.
Every time you have [] in your source code, you're guaranteed to get a
new (unique) empty list, and then multiple assignment will work.
*sigh*
Where were you three years ago? ;)
Actually, thinking about it a bit more, if we did that then one could not
use an empty list as an enum value. Why would one want to? No idea, but to
make it nearly impossible I'd want a much better reason than a minor
inconvenience:
I would normally expect enumerated values to be immutable and
hashable,
And, perhaps, to be actual enumerations. (So that in the set (a,b,c,d),
you don't know nor care about the underlying values, except that they
are distinct.)
