Incidentally, we'd also need introspection of arrays, to extract the

I spent a fair amount of time with Rakudo over the holiday break (see
http://dave.whipp.name/sw/perl6 for the writeup). I was generally
impressed with both the language and its implementation. There were,
unsurprisingly, a bunch of things missing. Some of these were things

In the general case, both the junction and the domain may be infinite:
my @domain = -Inf .. 3;
my $junc = any -4 .. Inf;
my @values = @domain |==| $junc;
say @values.perl
