I was too embarrassed of it to dwell on it, heh. Smilie And the one obvious way left to improve it to better work with your data -- eval, so the string a="some string" would be processed by the shell literally to set the variable a -- would open up gigantic security holes. Someone could name a song `rm -rf ~/` and it'd do it...

NAME
PPI::Token::QuoteLike - Quote-like operator abstract base class INHERITANCE
PPI::Token::QuoteLike isa PPI::Token isa PPI::Element DESCRIPTION
The "PPI::Token::QuoteLike" class is never instantiated, and simply provides a common abstract base class for the five quote-like operator classes. In PPI, a "quote-like" is the set of quote-like things that exclude the string quotes and regular expressions. The subclasses of "PPI::Token::QuoteLike" are: qw{} - PPI::Token::QuoteLike::Words `` - PPI::Token::QuoteLike::Backtick qx{} - PPI::Token::QuoteLike::Command qr// - PPI::Token::QuoteLike::Regexp <FOO> - PPI::Token::QuoteLike::Readline The names are hopefully obvious enough not to have to explain what each class is. See their pages for more details. You may note that the backtick and command quote-like are treated separately, even though they do the same thing. This is intentional, as the inherit from and are processed by two different parts of the PPI's quote engine. SUPPORT
