Thanks, yeah I considered using the instructions directly, but I was hoping for a more cross-platform option. For my purposes, developing in the Bevy engine, nightly isn't a huge blocker. Yeah, it would be really great to just have breakpoint support in stable Rust, thanks for doing the proposal! I'll consider stable support in the meantime.
Hah, the README says:
> Additonally, debugging may not land on the macro statements themselves.
See my comment above, and give int3;nop a try.
