Small suggestion (I haven't checked all the PR in detail): we could use something like ADDOP_ARTIFICIAL_JUMP instead of ADDOP_JUMP_NOLINE so is clear the kind of jump more than how it will behave

I think I prefer NOLINE to ARTIFICIAL. NOLINE explains what it does, ARTIFICIAL explains why.
I'd prefer the code to say what it does, and leave the "why" to comments.
I'll add a comment to explain why the opcode should have no line number.

Thanks for fixing it! The release dice were not in our favor: it missed being in 3.10.0a4 by one commit! |
