I’m forwarding this to the Perl 6 language list, so see if I can find an answer there. [This conversation is about how lexical subs should be implemented in Perl 5. What Perl 6 does may help in determining how to iron out the edge cases.] On Sat Jul 07 13:23:17 2012, sprout wrote: > On Sat

[perl #57126] Rakudo should give a nice error about lexical subs not being implemented yet, but doesn't

Hi, Thanks for reporting and helping track this one down - it was a fix in PCT in the end (in fact to the line immediately following the one you'd identified). So r29755 solves this, and probably will solve other similar issues too. Thanks! Jonathan
