::::::::::: I tried the perl implementation against this spec. It's broken. If I use the pattern ab{c,d\,e{f,g\h},i\,j{k,l\,m}n,o\,p}qr I see no result line which contains both an 'f' and a 'k'. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 01:10, 1 February 2014 (UTC)
:::::::::::: It would be incorrect if it did so, since f and k come from different alternatives, separated by the comma before the i. Alternatives separated by comma are expanded internally and exclusively from each other—one never takes a cross product over a comma, only over braces. --[[User:TimToady|TimToady]] ([[User talk:TimToady|talk]]) 02:01, 1 February 2014 (UTC)
