Well sure - who couldn't use the any() and all() functions? They're so useful that perl6 included them in the core. The idea is that you can say something like 5 == any( 1 .. 10 ) and have it evaluate true because one of the possible expressions is true. Similarly, all( 'marsh', 'munchkin', 'mink') =~ /^m/ would also be true because all the expressions evaluate to true. Obviously this is something that can be done in perl5 - it just requires more code.

Now as for actually using Q::S ... no. Its heavier weight than I'd prefer. My most common wish is for the two disjunctions - any of a list of regexes being true and any of a list of strings being equal. I just do those up as plain subs but its not as pretty as perl6 will let me be.

sub qrany { $_ =~ $_[0] and return 1 for @_[ 1 .. $#_ ]; return 0 }
sub eqany { $_ eq $_[0] and return 1 for @_[ 1 .. $#_ ]; return 0 }
