Barry suggested I bring this up here.

It seems the right time to at least discuss this:

RE: PEP 553 enabling / disabling breakpoints ---

I've recently started using a simple conditional breakpoint in ipython, and wonder if - in addition to Nick Coghlan's request for the env 'PYTHONBREAKPOINT' (boolean?), it would make sense (I think so) to add a condition parameter to the breakpoint() call. This does raise several questions, but it seems that it could make for a simple unified way to conditionally call an arbitrary debugger. What I found useful (in the contecxt of ipython - but general enough) you can see in this gist: https://gist.github.com/yarko/bdaa9d3178a6db03e160fdbabb3a9885

If PEP 553's breakpoint() were to follow this sort of interface (with "condition"), it raises a couple of questions:

I have no dog in the fight, but to raise the possibility (?) of having PEP 553 implement simple conditional breakpoint processing.

Any / all comments much appreciated.

Regards, Yarko

Yay, thanks! We’ll see if I can sneak that backport past Ned. :) -Barry
