It still has security issues. Anything in $(brackets) or `backticks`, eval will try to execute.

ppi::token::quotelike
PPI::Token::QuoteLike(3) User Contributed Perl Documentation PPI::Token::QuoteLike(3)
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
See the support section in the main module.
