  A second class you should look at Auto-XS'ifying is constants.
  
  Something like sub { 1 } turns into dramatically faster XS.

    That should be happening anyway, right? Perhaps only if you write sub () {1}.
    
    The next thing I might tackle is setters. However, since those come in a much wider variety than getters, it'll take some better matching tools than what we have now in B::Utils. Just look at the code of AutoXS::Accessor for a sample of what kind of cruft I produced.
    
    So as a yak shaving exercise, I'd like to write two routines: One that produces a pattern/condition structure for B::Util's opgrep() from an existing op tree and one th

      sub () { 1 } gets you part of the way.
      
      But the XS version is even faster again.

        How can a sub call be faster than compile-time constant folding?

      I just wrote the code to produce opgrep patterns from op trees (I.e. B::OP objects). Expect B::Utils 0.05_06 on CPAN soonish.
      
      Oh, and there is a typo in my last comment. The second code snippet is missing a closing ]. Sorry about that.
