in reply to About using rperl

I'm not an expert on rperl, but I think the answer to your third question should be obvious.

> Then, why not just write an XS-module?

XS modules are not easy to write. Being able to write high performance code in "pure" Perl should be an advantage.

    Yes I agree! It would be great to see an example of how to call a sub in the shared library from regular Perl code.

      I haven't seen such example of code, but I attended a talk by Will Braswell a few months ago, and asked whether it is feasible, and Will answered that it is possible. So you could have your CPU intensive nested loops or other computations in a RPerl module, and the rest in a regular Perl program. This looks very interesting to me, because it seems easier to write a RPerl module than an XS module.
        Please excuse my ignorance, but wouldn't this imply having two runtime environments for Perl communicating via sub calls?
