That's a different PSH. I did not release mine to CPAN in time and someone else released his. And I was too lazy to rename it. As far as mine goes ... it keeps accumulating lines until it finds one ending with a semicolon. I would not want it to print the return value of everything, if I want to eval and get the value I use

psh$ ? 10/5

It might be good if there was a REPL installed with Perl, but I bet most people would not use it anyway.
