To expose variables, SWIG actually generates two functions, to get and set the value. In this case, Foo_set and Foo_get would be generated. SWIG then automatically calls these functions when you get and set the variable-- in the former case creating a local copy in the interpreter of the C variables, and in the latter case copying an interpreter variables onto the C variable.
