Environment variable --------------------
Should we add an environment variable so that
sys.breakpointhook()can be set outside of the Python invocation? E.g.:: $ export PYTHONBREAKPOINTHOOK=my.debugger:Debugger This would provide execution environments such as IDEs which run Python code inside them, to set an internal breakpoint hook before any Python code executes.
Related to this is the suggestion that we make the default sys.breakpointhook() a no-op, so that accidentally checking in calls to breakpoint() won' t hang CI systems.
Then folks that wanted to use the functionality would set "PYTHONBREAKPOINTHOOK=pdb:set_trace"
Cheers, Nick.
