While it would be great if junctions were so native that they
distributed, assuming we can't do that in Perl 5, I think junctions
need to make it easier for people to map functions to the elements.
Then we need to teach people not to pass junctions to functions unless
those functions explictly expect junctions.
Effectively, we want to turn this:
any( map { is_prime($_) } any(1,2,3)->values )
Into this:
any(1,2,3)->map( \&is_prime )
I've submitted a Perl6::Junction ticket to that effect.
