in reply to Acme::Don't

How many time have you been working on some code and wanted to comment out a section of it to test specific code components?


q{ ...; ...; };
Perl will optimize this away, so there's no execution speed involved. Probably the best thing about this is that many color highlighting editors will mark this as a string (which it is), so you can see that it's something not-normal. BEGIN blocks are not BEGIN blocks anymore, they are just part of the never-executed string. It doesn't do any syntax checking (well, you do have to balance your {}'s, or have to choose other delimiters).

Update (Aug 15 2002):

15:07 <@kane_> juerd: it looks elegant, but wanrs =) 15:07 <@Juerd> kane_: I know, but it's perfect for development code. T +he warning is a good reminder, too 15:08 <@Juerd> I can't believe I didn't say anything about warnings in + that post... 15:12 <@Juerd> kane_: Hmmm... use Acme::Comment qw/start q{ end };/ wo +uld work, wouldn't it? :)

      Surely they're not quite the same? Acme::Don't's don't {...} is documented as returning undef. When used as the last line of a module, don't { 1 } isn't (sorry) the same as
      <<'comment' 1 comment
        I was just replying to the "how to make a comment part" - not the Acme::Don't. Who cares if they are the same or not? not me :)

        If undef is strictly required, then just:
        undef or do { ... };
