Re^4: Perl_API get_sv and SvIV_set

[BUU]

Well, I modified pp_next by adding a "DIE" call in the middle of it but no loop I tried could trigger it. Doesn't seem to be the one I want.

There is no such op. If you add a continue block, you'll notice that lineseq has three arguments/statements instead of just two. If you want to run something at the end of every loop, alter the optree to wire your op in.

Heh. Not a bad idea if that is the only way to do it. Unfortunately I lack experience doing evil things to perl. Any idea on where I should be looking to do so? I understand perly.y has the grammar, or what there is of it, but I was a little confused how I could make it add an op.

[diotalevi]

Read nodes by me that mention B::Generate and google for Simon Cozens' article "Where wizards fear to tread."

This node describes adding a new op to the grammar in Perl. I'm not sure if this is helpful to you but I remembered it when I read your node. Good luck.
