Since this is a Python 3k item... What would be the consequence of
making None the default value of an undefined name? And then assigning
a name to None as a way to delete it?
Some benefits
=============
*No more NamesError exceptions!
print value
>> None
value = 25
print value
>> 25
value = None #same as 'del value'
*No initialization needed for a while loop!
While not something:
if <condition>:
something = True
*Test if name exists without using a try-except!
if something == None:
something = value
*And of course one less keyword!
Any drawbacks?
Cheers,
Ron
PS... not much sleep last night, so this may not be well thought out.
