Perl REPL

[bmeneg]

So, while developing my application I noticed I wanted to make a simple test with grep { } @array and see grep's results on each different context (I didn't use grep for a while). Then, naturally, I invoked perl in the command line and declared some variables and ran the test I wanted, but then I remembered I could not just hit enter and see the results of my print $foo, but I had to send an EOF (ctrl+D) to the terminal. But hey... I lost all my declarations.. I wanted to carry them on and test other stuff... frustrating right?

Now, I know most of compiled languages don't have an REPL builtin (Common Lisp is a huge exception), but most of interpreters has, ie. Python. Now the question: do you guys think is it useful or am I crying for a lost cause?

I saw two REPL projects on CPAN:

1. https://metacpan.org/pod/Devel::REPL
2. https://metacpan.org/release/SUKRIA/perlconsole-0.4/view/perlconsole

The first is 8y+ with no updates, the second I have no idea on where is the code and the last changelog entry is from 2007.

Am I missing something or investing some time on a definitive REPL would be worthy?

(NOTE: Common Lisp REPL is just way above the curve... it has partial compilation, state awareness, object modification, ..., it's a complete compiler in form of REPL)
(NOTE2: The REPL idea doesn't necessarily fit perl-ide umbrella, but seems a good place to ask about)

Ok, I moved this conversation to Reddit, might be a better place to start a generic conversation around it.

The developer of Devel::REPL is easy enough to reach, if you wanted to explore that one further.

Hmm, interesting and good to know :) I'll try them out and let you know.
