We had some discussion in #111744 and in discord channel. We know this is a breaking change but people agree it's much more intuitive.

This basically changes the breakpoint() and pdb.set_trace() behavior so it stops immediately after the call, rather than before the next line.

Unfortunately a lot of the test cases need to be adapted.

Haha.

Away from my computer now, but I’ll take a look at this today.

Haha.

Pun is actually not intended. Took me a second to realize what's funny :)

This is a breaking change but I can't tell you how many times I wanted to look at the state of a function, I put breakpoint() at the last line... and it stopped after leaving the function altogether 😵‍💫

So this is great to see!
