I don't know if you noticed but I didn't say I preferred one rather
than the other . I just tried to say that language semantics dictate
that Michael's simplistic statement is not valid *in the general case*
I understand what you say, I had to implement something like this when
I tried to patch Trac's PyDocPlugin in order to support PEP 302 (e.g.
load modules from EGG files ...). In that case uniformity matters and
PyDocPlugin actually loads Py modules, so the *dot* notation might be
a good decision. Nonetheless , it was necessary to guess (on the
darkness) the boundaries between module imports and attribute access
(adding some extra complexity), mainly due to the fact that the
language + stdlib don't provide support for that OOTB.
OTOH under different conditions the *colon* notation is more explicit
(which is better than implicit) and this might help to figure out a
few things that can't be known if using the *dot* notation.
Probably complex is better than complicated .
I'd advocate for keeping both, if possible, and if leaving just one I
think I'd vote for the *colon* notation because it's more explicit ...
... but anyway people is gonna do what they're gonna do, isn't it ?
