The impact looks pretty minimal: the patch needs to do a little bit of
extra work in the optree cleanup/optimisation phase, and on method
lookup all the real magic occurs wrapped in a test:
if ((PL_op->op_flags & OPf_SPECIAL) && ...)
.. which test will succeed only if the pragma has been used.
Umm, personally I'd want to see some real figures before deciding.
The code itself also looks very clean, and I know that there are many people who'd like to be able to use perl in this way.
Yes, I have wanted to do this sort of thing in the past myself. A question: doesn't this overlap to some degree with what you can do with overload?
p.s. chocolateboy: who he?
