Well, the *real* reason I used a __dict__ extraction was because I didn't
think of using getattr at the time, but as a post facto justification,
I'll point at the difficulty in using getattr for extracting a function
from the current module:
>>> def f(x):
... return x + 1
...
>>> func = getattr(???, 'f') # what should go there?
Maybe I've just got a blind spot, but I can't think of a way to use
getattr to get something from the current module. That would lead to
something like this:
def get_function_from_name(name, module=None):
if module is None:
return globals()[name] # or use locals()
else:
return getattr(name, module)
which is fine, I suppose, and I would have used it earlier if I had
thought of it *wink*
