I know that. That was what I meant by "changing the order of the definitions
will work" in my original message.
And I insist in the issue, which is not trivial... In my message I mentioned
"crossed recursion", and I delve into it here:
Suppose I have to define two functions, aa, and, bb that are designed to call
each other:
def aa():
...
... a call of bb() somewhere in the body of aa
...
def bb():
...
... a call of aa() somewhere in the body of bb
...
Whatever the order of definition of aa and bb the problem remains, one of the
two identifiers is not known ...
Most of computer languages have mechanisms to deal with this issue. Is there
any
in Python or it is in disadvantage with respect to other languages like C++,
Java, Perl, PHP, etc.?
