C::Blocks—embeding a fast C compiler directly into your Perl parser—looks exciting to me. I hope it will be interesting to some of you and since this is a project in its infancy maybe even inspire participation from the C-monk(ey)s here. Google groups notice: https://groups.google.com/forum/#!topic/perl.xs/35CgBxWmqEk; github repo: https://github.com/run4flat/C-Blocks.

I have no involvement but have had some pain in the past trying to do XS so I welcome anything that makes embedded C, or even just playing with it from Perl, easier.
