could you give some technical detail on this?
i don't know compiler so am probably being foolish here... but i
suppose ultimately name resolution and storage at heart is something
like a hashtable... namely,
put ‹identifier 1› table
put ‹identifier 2› table
and lookup is just
retrieve ‹identifier› table
and now suppose we introduced namespace, so i imagine the compiler
simply just concat namespace component befor put, and split before
retrieve?
