Hmmm, in the more general case of:
for (my $i = intializer(); condition($i); $i = advance($i)) { ... }
where you might want $i to be lexically scoped in the for loop, is there a
way to do it?
Perhaps something like:
initalizer() -> $i { LOOP: NEXT { $i = advance($i); redo LOOP if
condition($i);} ... }
except I'm not sure that that would have the same semantics.
(Or, more generally, given a for loop with a "my", how sould perl52perl6
deal with it?
