++ I like this, although I'm starting to think that I had just misunderstood join and should probably go with an alternate solution rather than shoehorn join to my way of thinking.

    Somewhere else in this thread $a and $b were mentioned. The snippet above could be changed to use this. Instead of

    $res .= $sub->($_[$i-1], $_[$i]) . $_[$i];

    it would be 

    local $a = $_[$i-1];
local $b = $_[$i];
$res .= $sub->() . $_[$i];
