You do not need to modify the compiler to do this (unless you want to
change the syntax which is what Peter proposes).

The key is to define a new class definition message which allow you to
specify which variables are to be exported. The key issue is to track
all class modification to add/remove the methods according to instance
variable additions/removals.

In fact when you do an accept in the Browser text pane the Compiler
simply evaluate the expression printed.
