Any

Any is the root of the class. It's like Perl 6's Mu, (confusingly Str is more like Perl 6's Any). Any has no methods yet. The main role it plays is to be Spit's "void" context:

my $a = "foo";
my $b = "bar";
True ?? $a !! $b; # $a and $b are in Any context
say True ?? $a !! $b; # $a and $b are in Str context
