Thanks. but I meant more within the same class: before I was using
class inheritance to ensure that I don't have to worry about ordering.
Now I will use includes as you suggest. Say I have a class that has an
include, is there a guarantee that the include will always be included
before the rest of the class is examined?

I mean withint the same class. Say I have a case statement at the top
of my class that sets a variable, will that run before I need the
variable (later in the same class)?
Sorry for the confusion.
