Probably that [c.l.]python is becoming more popular and, like most
things as they become popular, it loses its "purity"... much like the
Internet in the early 1990s.

No, that's invalid syntax:

Say I have module foo.py:
def a(x):
def b():
x
del x
If I run foo.py under Python 2.4.4 I get:
File "foo.py", line 4
del x
SyntaxError: can not delete variable 'x' referenced in nested
scope
Under Python
I'm looking at a person's code and I see a lot of stuff like this:
def myfunction():
# do some stuff stuff
my_string = function_that_returns_string()
# do some stuff with my_string
del my_string
# do some other stuff
