Possibly a FAQ, but is there a simple way of asking if an item is
contained in an array? I know of $x ~~ any(@array) and @array.grep({
$_ ~~ $x}), but those both seem a bit complicated for a conceptually
simple test, so I'm wondering if I'm missing something.
Note that grep doesn't have to take a closure, but can also take just
the value you're looking for...

1
0
Though more efficient would be:
> my @x = 1,2,3; say ?...@x.first(2); say ?...@x.first(4);
1
0
I still prefer the junction way though. :-)
