A global switch in the sys module would make life a lot easier. Even better would be a context manager that allows us to set up a "numerical" context for local expressions using a with statement. That would not have a lasting effect, but just affect the context. Preferably it should not even propagate across function calls. Something like this:
def foobar(): 1/0.0 # raise an exception 1/0 # raise an exception
with sys.numerical: 1/0.0 # return inf 1/0 # return 0 foobar()
Not propagating across function calls strikes me as messy, but I see why you'd want it. Would this be better as a __future__ directive? There's already the concept that they apply to a module but not to what that module calls. ChrisA
