I've created a class that has a property which points at a private
list. When I try to use the append() function on this list property,
the fget method is fired rather than the fset method. If I directly
set my property to a literal list, the set method fires.

When you create a new process, you have the option to inherit
file handles to the new process. So the parent should open the
file, and then inherit the handle to the new process.

Working on parser for my language, I see that all classes (Token,

logical to have them all inherit from a base class that defines those,
