- string.find should return index of found character + carry set if found, carry clear if not found. (fix cx16assem, it uses current behavior. Also fix docs!)
- if char in "string" should fall back to string.find if string is longer than... 16? - if char in "string" should fall back to string.find if string is longer than... 16?
also.. is "string" removed from the interned strings?

CallGraph can then also only store IdentifierRef instead of pair(ident, position) as keys. - IdentifierReference: fix equality to also include position.
