[Python-ideas] breakpoint(): print(*args, **kwargs) before entering pdb

[Carl Bordum Hansen]

I played around with a newer Python build, but when using the new 
`breakpoint` builtin, I missed my weapon of choice: dirty print-debugging.

I suggest we combine forces and make the default `sys.breakpointhook` 
forward *args and **kwargs to print before entering pdb.
