Yeah, junctions are super useful, but not very fast.
compare these two pieces of code:
so "hello how are you today?".contains("hello" & "u t") for ^1_000_000
and
my $target = "hello how are you today?"; so
$target.contains("hello") && $target.contains("u t") for ^1_000_000
On my machine i get 25.7s for the first one and 1.5s for the second one.
