PL/1 still exists, although as a niche language practically limited to mainframes. Along with being a base for C it also was probably the first programming language that introduced exceptions as mainstream language feature. Also IMHO it is the origin of functions substr, index and translate as we know them. Compilers from PL/1 were real masterpieces of software engineering and probably in many aspects remain unsurpassed.

What is common between PL/1 and Perl is the amount of unjustified hate from CS departments and users of other languages toward them.

What I think is common about both is that, while being very unorthodox, they are expressive and useful. Fun to program with. As Larry Wall said: "Perl is, in intent, a cleaned up and summarized version of that wonderful semi-natural language known as 'Unix'."

Unorthodox nature and solutions in Perl which stems from Unix shell is probably what makes people coming from Python/Java/JavaScript background hate it.
