There's no question you instantiate a substantial number of arrays and hash tables in your program. Maybe most of them are global variables, but you still spawn several instances of arrays and hash tables. You do not have a single giant array and a single giant hash table, you have several of them.

Same thing with parsers. Lex/Yacc used to allow only one parser of any kind in the whole program. But if you want to parse 2 languages, you need 2 parsers. Of course, you'd need only one parser per language, and perhaps those two parsers parser's state will be stored in global/static variables. You still instantiated 2 parsers.

At least that's how I understand "instantiation".
