We should add a roadmap to the book that says what features are coming

hello, I find wit intresting. specifically around primitive types and records.

i see tuples can emulate fixed size lists like.
'type fixed_u8_22 = tuple<u8, u8, .... 29 more, ... u8>'
what is max limit suggested for tuple size? we do not need more than 64 items in tuple.
are there plans to have fixed size lists like?

other question.
what do you think about 'sorted unique' maps and sets(but not unsorted unique maps ans sets) and 'sorted' lists?
may be in form of structured doc comments or attributes to specify it?

Great questions, and I've certainly wished for a WIT map type a few times. Although please bear in mind that WIT is an IDL (Interface Definition Language), not a standard library, and is constrained to try to map well into as many languages as possible - very specific types like "sorted unique map" are likely to be out of scope. In any event, you'll likely get better answers to roadmap questions on the component model GitHub (https://github.com/WebAssembly/WASI) or in the Bytecode Alliance Zulip (https://bytecodealliance.zulipchat.com/) - this repo focuses on as-is developer documentation for the component model.

Found fixed types here WebAssembly/component-model#181 and dictionaries WebAssembly/component-model#125 and structured annotations WebAssembly/component-model#58
