Put expression types of procedures in type table
Before we annotated the AST. But that is silly in hindsight:
certain operations have a completely different meaning when applied
in a polymorphic context (i.e. the field index determined by a
select expression).

- Reowolf's pseudo-socket API mimics the API of UDP sockets
- This example corresponds closely with that of the socket API, differing only in:
1. an added import of the pseudo-socket header file
2. (pseudo-)socket operations' identifiers are prefixed with `rw_` (short for "Reowolf").
