Help with simple meta programming


This is a basic question of meta-programming with Ruby, which I'm
still getting familiar with.

I want to change/create a new attr_accessor such that it calls a kind
of proxy for retrieving the variable (which is not actually stored in
the object itself but rather on the database).

def variable

def variable=(value)
  invoke_method(variable, value)

So, I catch the method name which should correspond to the variable
(except for the set method, which includes an extra '=') and pass it
to another function.

Any hints on how to get it done the right way? Thanks!
