Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

• Operating System & Odin Version:
• Please paste odin report output:

        Odin: dev-2023-11:04244041
        OS:   Ubuntu 22.04.3 LTS, Linux 5.15.133.1-microsoft-standard-WSL2
        CPU:  12th Gen Intel(R) Core(TM) i7-12700H
        RAM:  15838 MiB

Expected Behavior

Please describe the behavior you are expecting

field_matrix :: proc(
	$N: int,
) -> (
	result: matrix[N, N]int,
) {
  return
}

or

field_matrix :: proc(
	$N: int,
) -> (
	result: matrix[N, N]int,
) where N <= 4 {
  return
}

should both work. The following without matrix however does work

field_matrix :: proc(
	$N: int,
) -> (
	result: [N][N]int,
) {
  return
}

works

Current Behavior

compiler would complain

Error: Invalid matrix row count, expected 1+ rows, got N
        ) -> matrix[N, N]int {
Error: Invalid matrix column count, expected 1+ rows, got N
        ) -> matrix[N, N]int {

Failure Information (for bugs)

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Use matrix in parapoly function declaration
2. Compile
3. Won't compile

I also found that the following is allowed, so it seems that this bug only happens inside the declaration

field_matrix :: proc($N: int) -> any where N <= 4 {
    result: matrix[N, N]int
    return result
}

Found some more interesting behavior...
This is not legal

field_matrix :: proc($N: int, m: matrix[N, N]int) -> int where N <= 4 {
    return N
}

But this IS legal and used in the core library

field_matrix :: proc(m: matrix[$N, N]int) -> int where N <= 4 {
    return N
}

I'm currently trying to debug this and I'm not sure how this happens yet as I'm not too familiar with the codebase

I encountered this one just now. It was the second procedure I ever wrote in Odin, in first hour of experimentation. Couldn't figure out what I was doing wrong. My luck :)
