Thanks for the explanation, japhy++! Playing around with your code I think I understand it now and how I accidently created a closure. I still have some questions, though.

• Why is the regex not recompiled, I'm not using the /o modifier. I thought perl recompiles a regex /$p/ which contains a variable interpolation every time. And is there a way to force a recompile?
• I was not trying to do anything funny with the different scopes. What I want is execute some code which manipulates a variable in a regex. And I'd like to use a lexical variable so that I don't pollute the global namespace. Is there a way to do that? Taking the my @x declaration out of the loop like this

  my @x;
  for (0..2) {
    @x = (0);
    "ab" =~ $p;
    push @r, \@x;
  }

  fixes it here but what if the whole thing is in a subroutine, then I can't call it more than once, can I?
• I think I'm not wrong in saying that this is slightly underdocumented ... especially since 5.6.0 seems to behave differently as others have posted here.
