[Python-projects] Bug in pylint ? Looks like pylint 0.14.0 can't detect mismatch in function arguments!

huum, I'm afraid that this has never been implemented in pylint (yet).
The only thing that has been done is checking of argument consistency
when defining/overriding *methods*. Function/methods calls aren't
checked, though this could be done quite easily now that we have a
better inference mecanism. The problem is that, as you may have noticed, 
i'm really missing some time to work on pylint those days. For instance 
I've started a few months ago some work on astng to have it working using
either the compiler module or the new _ast of python 2.5 but I've not
yet found the time to finalize it. Hope I'll get some time back in a
near future for the pending stuff I've in mind for pylint. I'll include
function calls checking in this, I've created a ticket for this so I
wont forget: http://www.logilab.org/ticket/5561.

Thank you for the already written test file ;)
Cheers,
