Re: smart match operator should be smarter!

Ok, thanks. I see that my last problem is the same problem: you can't use the match operator with a literal. So you have to do this:

my @arr1 = (2, 34);
my $val = 34;

say "34" if $val ~~ @arr1;  #34

But the smart match operator is supposed to be commutative, yet:

my @arr1 = (2, 34);
my $val = 34;
say "34" if @arr1 ~~ $val;

#no output...??

Fixing the aforementioned bugs required making ~~ non-commutative. I don't see any aforementioned bugs??? Ok, so not commutative anymore. Another flea from the llama 5th bit me.	[reply]

It made overloading ~~ impossibly complex. I think there were other problems too. If you use given/when, you shouldn't notice a difference.	[reply]
