assignment hook

[paul.lafollette at gmail.com]

Kind people,
Is there any way one can, within Python, intercept the act of
assignment.  For instance, suppose that I was obsessed with
FORTRAN II, and decided that I wanted to print a warning,
or raise an exception any time someone assigned an int to a
variable whose name did not start with i,j,k,l,m, or n.

If assigment were an operator, I could, perhaps,  subclass
something and override the (non-existant)__assign__ method
to find the name of the variable and the type of the assigned
object, but it ain't so I can't.

My guess is that it is simply impossible, but if it IS possible,
I would love to know how to do it.  Thank you for your time
and expertise.

Paul
