greg 6d93c758a2 Add function to symbol table 2018-07-26 00:52:46 -07:00
greg aff421cd99 Working with symbol table 
Note that symbol table is a different object now than the previous
binding table that was used for type-checking. That binding table is not
currently debugged and should be debugged in a separate debug output with
typechecking proper.
