Then you'll have to use one, but it will have to store all the variables
with the same name. It will also have to have some way to tell them apart.
One structure that I've used is to label all the scopes (functions,
classes, compound statements, ...), and store that along with the
definition, Then you can find the right definition by remembering which
scopes are active.
This works well in the typical case where there is only one definition,
and correctly in the case where they all have the same name. It also makes
entering and exiting scopes nearly free.
