@jiel-nv Many thanks for the PR! I'll add it to my queue to review, but note I'm OOO until next Tuesday, so will have to pick it up after then. |

If I comment out all these checks then none of the debuginfo tests fail. It's not immediately obvious to me what these conditions are for (I was commenting them out to try to learn what they did by what breaks when I do that) - are they really needed? If so, what for? Are there additional tests needed to check for the conditions these handle?

Ah, I see now that the first two conditions are used in the superclass storevar() and suppresses storing the variable when they are true.
I think the last is because we don't emit debuginfo for internal names (those beginning with a $).

I think this generally looks good - there is one suggestion on the diff which I think will save time for future readers of the code (it took me quite a while to work out).
