I may be off base here, or in the alternate pointing out a corner case
that's of little significance, but:
-Compound statements: if($foo eq "a" or $foo eq "b" or $foo eq "c") {...} ->
if $foo eq "a"|"b"|"c" {...}
Is there an issue if $foo is tied here, in that (unless the a or b condition
match) $foo will be evaluated three times; for testing against a junction is
it feasible that the compiler can say "aha, I'll only evaluate $foo once and
test it three times"? Reading $foo may have some real world visible effects
and the semantics would change. The P6 spec may nail this down, but I
haven't time to go look (and I'll surely not have time before I forgot this
thought completely...)
That's all I can pick out from the quick glance I have time for. Have fun!
