Perl 6 Version​:

This is perl6 version 2015.09-428-g46874fd built on MoarVM version
2015.09-79-gee9fc2b

When I try to run this program in the debugger​:

#!/usr/bin/env perl6

use v6;

foo();
bar();

sub foo {
  say 'foo';
} # END​: foo

sub bar {
  say 'bar';
} # END​: bar

I get this from the debugger​:

$ perl6-debug-m comment_bug.p6

LOADING comment_bug.p6
===SORRY!=== Error while compiling
/development/perl6/introduction_to_perl_6/functions/comment_bug.p6
Strange text after block (missing semicolon or comma?)
at /development/perl6/introduction_to_perl_6/functions/comment_bug.p6​:12
------> }⏏ # END​: foo
  expecting any of​:
  infix
  infix stopper
  statement end
  statement modifier
  statement modifier loop

It apparently only happens if there is code after sub foo {...}. Thanks!
