Re: Re: Block commenting

Not a very good idea, as the comment still is interpolated:

use strict;
<<COMMENT;
$foo = 'bar';
COMMENT
[download]

gives:

Global symbol "$foo" requires explicit package name at line 3.
[download]

Abigail-II's suggestion of Acme::Comment is pretty serious, if you really want to have multi-line comments the way you want them. Personally, I think Acme::Comment lives in the wrong namespace: it should probably live in the Filter::Comment namespace or so.

Personally, I think Acme::Comment lives in the wrong namespace: it should probably live in the Filter::Comment namespace or so. I disagree with that. I think that namespaces like `Filter::` and `Tie::` should be restricted to module that deal with filtering or tieing. It's just not right to make the implementation part of the name space. Just think about it, should all modules that use objects belong in the `OO::*` name space? And what are you going to do with a module that uses a filter, is hence named `Filter::Whatever`, and then modifies its implementation so that it uses a different technique? It's a bad, bad suggestion. Abigail	[reply]

Whatever. I think we agree that the Acme:: namespace is even more inappropriate. I personally don't care much where it winds up. Anything better than Acme::. Liz	[reply]

`use strict; use warnings; <<'COMMENT'; $foo = 'bar'; COMMENT` [download] Will avoid the interpolation. But you will still get `Useless use of a constant in void context at temp.pl line 3.` [download] To avoid that you can do: `use strict; use warnings; { no warnings; <<'COMMENT'; $foo = 'bar'; COMMENT }` [download] But that is a lot of work. -- flounder	[reply] [d/l] [select]

Thanks++ for pointing out that the comment is interpolated. However to fix this, I would simply add single quotes around the COMMENT to prevent the HEREDOC to be interpolated. `use strict; <<'COMMENT' $foo = 'bar'; COMMENT ;` [download]	[reply] [d/l]
