The more advanced problem I wanted to solve, a two dimensional array of
functions, once this example is understood, becomes trivial to implement. In
fact, the more interesting problem I wanted to solve invo

In C, C++, Ada, and functional languages, I can create an array of functions,
albeit with the nastiness of pointers in the C family. For example, an array
of functions where each function is an active button, or an array of functions
that behave like formulae in a spreadsheet. I am finding

I think this is the most Pythonic idiom. You can even define your own
custom binary operators, such as '$' to convert dollars and cents to

Then EXPR OPER EXPR -> ops[ OPER ]( EXPR, EXPR ), right?

My parser has found an expression of the form CONSTANT_INTEGER
OPERATOR CONSTANT_INTEGER. I want to fold this into a single
CONSTANT_INTEGER.
The OPERATOR token has an intValue attribute, '+' == 0, '-'== 1, etc.
In C I'd put functions Add, Subtract, ... into an array and call

def f():

I have a table of integers and each time I look up a value from the table
I want to call a function using the table entry as an index into an array
whose values are the different functions. I haven't seen anything on how
to do this in python.
