Cool, thanks.
Stack inspection of sorts it is.

I'm not sure this is possible, but it sure would help me if I could do it.
Can a function learn the name of the variable that the caller used to
pass it a value? For example:
def test(x):
print x
val = 100
test(val)
Is it possible for function "test()" to find out that the variable it is
passed, "x", was called "val" by the caller?
Some kind of stack inspection?
Perhaps, but don't try it ;-)
Any help greatly appreciated,

Can't you use keyword arguments?
>>> def test(**kw):
... print kw
...
>>> test(val=3)
{'val': 3}
>>> test(val=3, otherval = 4)
{'otherval': 4, 'val': 3}
>>>
