    This is a monthly report by Dave Mitchell on his grant under Perl 5 Core Maintenance Fund. We thank the TPF sponsors to make this grant possible.

  • March report of the Perl 6 Development Grant of Jonathan Worthington Mon, 29-Apr-2019 by Matthias Bloch

    Jonathan writes: March saw me spending rather little time on my Perl 6 grant. I merged various optimizations I developed during February, but held back to merge until after the March release in order that they could receive more testing before appearing in a release. I also did a few other minor optimizations, and fixed a performance regression introduced during a recent bug fix. During March, I attended the German

  • February report of the Perl 6 Development Grant of Jonathan Worthington Fri, 15-Mar-2019 by Matthias Bloch

I also made allocation profiling aware of scalar replacement, meaning profiling does not block
