permute( @x_chars ) �{ $^a eq $^b ?? $^a :: ''}� permute( @y_chars )
Permutation is the wrong thing here, sorry. It's just:
( @x_chars �xx� @y_chars.elems ) # or was that .size?
�{ $^a eq $^b ?? $^a :: ''}�
( @y_chars xx @x_chars.elems ) # note: no hyperinge.g. <a b c> and <x y> give <a a b b c c> �{...}� <x y x y x y>
and finally a list of six empty strings.And look Mami, all without junctions! Lots of french ... ehm, freedom quotes involved, though :) -- TSa (Thomas Sandla�)
