Here's my problem. I'm traversing all the statements in the file looking 
for specific function calls. That is given the name of several function 
calls, I have to identify them, their parameter list and the LHS of the 
call (if it has one). I'm pretty sure your Iterator_Expr class will be 
very useful. Thanks a lot!
