Bug in handling of single underscore identifiers?

Today I installed the 'mechanoid' package from sourceforge, but the
self-test failed. On looking into it, I noticed odd behaviour in the
handling of single underscore module names. Importing into the
current namespace with 'from' seems to work, but accessing members of
the imported module only works if the imported name is qualified by
the containing module name.

For example:
from mechanoid import _mechanoid_Comm on
from _mechanoid_Comm on import Common Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: No module named _mechanoid_Comm on from mechanoid._mech anoid_Common import Common **succeeds** _mechanoid_Comm on

<module 'mechanoid._mec hanoid_Common' from
'mechanoid\_mec hanoid_Common.p yc'>

Is this a bug or a feature? The language reference section 2.3.2
'Reserved classes of identifiers' indicates that identifiers starting
with a single underscore are not imported by "from module import *".
However I can't find any indication that "from module import _name"
should work this way.

Thanks

Tom

Is there an elegant way to check for the REFERENTIAL INTEGRITY VIOLATION in Access via ASP. The reason I ask is that if the user attempts to refresh the screen after implementing an INSERT he will be trying to insert an identical record which thows up the following error (below). I could place On error resume next before but I find this dangerous or am I overworrying. I could preface the insert by doing a check for the record but this...

Hi all, Been a while since I've done any asp coding, but happy to be getting back into it. My question is what is the best way (now) to handle apostrophes coming in from forms and going into the database? I remember I used to use a replace function replacing single quotes with two single quotes in one of my old apps. Is this still the best way, use this function on all fields I think an apostrophe may come in, or on all fields? Or...

The main two desirable things I feel error handling should provide are these: 1) Debugging and diagnostic aid 2) User feedback One method that is used a fair amount it to 'say' that all functions must return an error code of a standard type, for example tError. Where tError is typedefed as a long int. A list of error codes may then be defined in a global header file, or perhaps upper bits of tError may indicate a module

I know that functions starting with an underscore, or two underscores, are reserved by the compiler/c++ and should not be used by the user and may cause undefined behavior. My question is, how likely is it to actually cause undefined behavior? The reason I'm asking is I'm using a game engine where the sockets code is not working correctly on my computer, but seems to work correctly on everyone elses. I am not compiling the dll myself,...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
