Hi everybody,
That was nice to meet many of you in person at YAPC::EU,
I am trying to learn about continuations and Parrot. I hit a
problem of register allocation. I don't know if it is a
miscomprehension from me or a bug. Probably the former.
Apparently P16 is used both for my Perlhash and the Sub.
Below are the beginning of a pdb session and the PIR listing.
