I think before considering any design you should be clear that the
language for which you are designing such symbol table design is
static scoped or dynamic scoped language.

As in case of dynamic scope language what ever you want i.e. symbol
should be searched form innermost function to the outer most function
in function nesting depth is done at run time using runtime stack and
there is different approach to tackle it i.e. either using the
displays (array of static pointers of activation record) or by
following the static link in each activation record to search the
occurrence of variable in the activation above it in run time stack.
