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

[Pierre Rouleau]

Hi.  I think I'v found a bug in Pylint 0.14.0

In the test file included below, Pylint 0.14.0 fails to report calls 
with invalid number of arguments!  I tried it on a directory with no 
rcfile just to be sure.  That's got to be a new bug, I'm sure I'v seen 
report of invalid number of arguments before with Pylint.

At first I ran it with logilab common 0.29.1.  Then I noticed that 
common 0.33.0 was available; I downloaded it and tried the test gain: no 
change.

This is got to be a *major* bug.  Am I missing something here? I am a 
little tired, having worked several nights to complete something at 
work.  But I was sure pylint was able to detect these mismatch 
before...  Somehow, now, pylint 0.14.0 accepts invalid calls...

Don't get me wrong.  I love pylint.  I use it all the time.  That's why 
I coul not beleive when I got a traceback on a function that was not 
passed the right number of arguments...  Anyway, if there is a switch I 
missed let me know. 

Thanks!
