Not in particular. But if you're working on making debugger entry more
discoverable/human-friendly, then providing a friendlier alias for the
pdb.pm() semantics might be useful too?
Actually, if you look at the pdb docs, the 3 ways of entering the
debugger that merit demonstrations at the top of the manual page are:
pdb.run("...code...") # "I want to debug this code"
pdb.set_trace() # "break here"
pdb.pm() # "wtf just happened?"
The set_trace() name is particularly opaque, but if we're talking
about adding a friendly debugger abstraction layer then I'd at least
think about whether to make it cover all three of these.
