How can I start an interactive console for Perl?

Question

How can I start an interactive console for Perl, similar to the irb command for Ruby or python for Python?

Answer 1

I always did:

rlwrap perl -wlne'eval;print$@if$@'

With 5.10, I've switched to:

rlwrap perl -wnE'say eval()//$@'

(rlwrap is optional)
