::Actually, there ''does'' seem to be a bug in the latest revision of the Perl 6 solution (which wasn't present in the original revision). Either that, or the Rakudo Star version I'm using to test it is too old or something. Because ''without'' the inserted X / Y, it only prints 2 expansions for that test case. --[[User:Smls|Smls]] ([[User talk:Smls|talk]]) 19:07, 31 January 2014 (UTC)
:::You don't have latest version, which I fixed in the last hour. --[[User:TimToady|TimToady]] ([[User talk:TimToady|talk]]) 19:13, 31 January 2014 (UTC)
::::You're right, the latest revision does in fact work correctly again. My mistake. --[[User:Smls|Smls]] ([[User talk:Smls|talk]]) 19:22, 31 January 2014 (UTC)
:The reference solution (Perl, not Perl 6) does agree with the spec: There should be no suppression of duplicates. As for the test case you mention, it has '''four''' expansions and not eight, because nested brace groups only expand the "branch" they belong to. For example, the pattern <code>aa{,{,11}cc}22</code> has three expansions (<code>aa22</code> <code>aacc22</code> <code>aa11cc22</code>), not four. --[[User:Smls|Smls]] ([[User talk:Smls|talk]]) 18:58, 31 January 2014 (UTC)
