Yes: first of all, this is why i called it a SKETCH, rather than a SOLUTION in first place. And, comparing the original with your version, what you did was to remove the line break, (see the quoted part above) which is exactly the reason why it doesn't stop looping: you took the stop out!

Another thing: one of the reasons you only get - very generalised - sketches (instead of more specific solutions) here is that you didn't tell us anything about your requirements: OS, used version, used shell, .... But then again, maybe i shouldn't explain that but instead just answer

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.
