Wish there was an error message

[kwasi007uk at yahoo.co.uk]

I was using poplib's example as in the documentation. Unfortunately I 
typed in the following at the end of the script:

M.quit instead of M.quit()!

I forgot the parenthesis. The effect was, that my pop-server produced 
really strange things, doubled the number of messages each time I 
queried it with poplib.

But M.quit does not exist. So it should give me an error message? Why 
doesn't it? Can I turn it on somehow?
