This means either the task description is buggy or the reference implementation is buggy. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 18:31, 31 January 2014 (UTC)
:Well, I believe the task actually refers to the Perl (5) implementation, not the Perl 6 one. But leaving that aside, there's no duplicate suppression taking place here. Note what happens when I run these (through the Perl 6 version):
<pre>{X,{Y,gotta have{ ,\, again\, }}more }cowbell!
Xcowbell!
Ymore cowbell!
gotta have more cowbell!
gotta have\, again\, more cowbell!
{a,a,b}
a
a
b</pre>
:We still get four entries for the first one, and the dupes aren't removed from the second one. I don't know what you're doing different, offhand, perhaps not throwing away stuff when you backtrack? --[[User:TimToady|TimToady]] ([[User talk:TimToady|talk]]) 18:54, 31 January 2014 (UTC)
