Re^3: slashes in single-quoted string

IMHO it's impossible to disable "escaping" and allowing arbitrary character sequences.

I mean by using an alternate delimiter like q{} or q// the problem is just postponed.

  DB<105> print q{\}}
}

Then the only possibility left would be concatenating with a constant representing the delimiter:

eval( '$string=' . QUOTE . 'abc' . QUOTE );

instead of eval( '$string=\'abc\'' );

Possible ... but desirable?

Cheers Rolf

UPDATE: or eval( '$string=' . q{'} . 'abc' . q{'} );

For most practical purposes, this likely wouldn't be an issue (or less of an issue that having to remember to take care of the special cases `\\` and `\<DELIMITER>`). And in those remaining few cases, you could still resort to concatenation, as you're saying. But why write silly things like `'$string=' . q{'} . '}' . q{'}` as long as can simply say `q\|$string='}'\|` ? That said, I personally don't really have problems with the way it's implemented currently.	[reply] [d/l] [select]
