<masak> jnthn: does this look right to you?

<TimToady> looks right to me
<masak> good enough for me :)
<TimToady> shouldn't need the parens, either
<masak> right. just making sure.
<TimToady> pugs: for "a".."c" Z "?", "a".."b" -> $x1, $x2 { say $x1, $x2 }
<p6eval> pugs: OUTPUT«a?ba␤cb␤»
<jnthn> rakudo: say "a".."c" Z "?", "a".."b";
<p6eval> rakudo a0a390: OUTPUT«a?bab␤»

>From the last example, we see that there's a 'c' missing from the
