I'm building a symbol table for a project I'm working on. I was wondering what peoples opinions are on the advantages and disadvantages of the various methods available for storing + creating a symbol table.

In our class we have talked about static chains and displays. I think that I understand why we need these. Otherwise when we have nested methods we cannot figure out...
