iundefined is really defined

[Skaperen]

in the latest testing iteration of this code, at line 83 i am trying to return a reference to a function named close which is defined in line 63. yet i get the message that it is not defined. what can cause this?

here is the output:

Output:
lt2a/phil /home/phil 296> py trytopen.py

any ideas?
