Bug with [] as default value in functions? - bug.py (0/1)

[Dinu Gherman]

Hi,

I noticed a very strange behaviour: I've got a recursive function like
this:

  foo(spam, eggs=[]):
    ...
    return foo(spam, eggs=eggs

where the default argument for eggs, the empty list, is *empty* for
the top-level call only when it is explicitly provided with the func-
tion call like this:

  bar = foo(mySpam, eggs=[])

I've attached a more lengthy example showing, I hope, rather pre-
cisely what I mean.

Is this a bug or just a lack of understanding of recursion and name
spaces, delicate as they are, in my brain??

Regards,

Dinu
