However you did give me an idea which does work (and I think does not have security issues)...
It still has security issues. Anything in $(brackets) or `backticks`, eval will try to execute.

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
