I think two separate functions would be better.

void interpreter::exec( const std::string& code, dict& globals, dict& 
locals );
- Executes the given code in the context of the two given dictionaries.

object interpreter::eval( const std::string& expr, dict& globals, dict& 
locals );
- Evaluates the Python expression given, in the context of the two 
dictionaries, and returns the resulting object.

They're equivalent to the "exec" statement and to the "eval" builtin 
function in python.
