In thinking about how to write a "partition" function (or separate, or
whatever you want to call it) it occurs to me that you might want some
sort of reverse-varargs behavior, like
my (@a, @b, @c, @d) = @array.partiton { $_ % 4 };
So in this case, partition is supposed to determine, on the fly, how
many classes to return (or return all the classes it makes, and let an
exception take mismatches).
How do we do that?
And in general, without resorting to something hideous like scanf, is
there going to be some more-advanced want() variant that allows saying
@a, $i, $j, @b, %w, $k, @c = scramble(...);
