  • I'm also having trouble doing this. The best reference I've found so far is Simon's 'use Python' paper in last year's TPC proceedings. He has an example of creating a new anonymous sub, calling svref_2object() on it, and manipulating its START and ROOT ops.

    I can get pretty close, but never quite avoid the segfaults. It probably doesn't help that I'm trying to pass the rewritten subref to B::Deparse, either.

    • Thanks for the tip. I had read Simon's paper last year when I got into this project (and scanned it at TPC), but had completely forgotten that he did just what I wanted in the paper. I've now got working code that creates an anon. sub which contains the code from the main_cv (minus the enter and leave ops). Little tweaks are necessary for things like constants that are optimized away and need to be reset with the sv method, but it looks to be working.

      Thanks again!
