Add primitive function and table types
Summary
Add types for "real" functions and tables.
Motivation
Some APIs require "real" functions and tables, not just things that
"look functiony" (e.g. tables with a __call__
metamethod) or "look
tabley" (e.g. instances of classes). This RFC adds types for those.
Design
Add:
- a type
table
, inhabited by Luau tables (but not class instances), and - a type
function
, inhabited by Luau functions (but not class methods or tables with metamethods).
Drawbacks
Why should we not do this?
