Error message improvement suggestion

[chris-montero]

Is your feature request related to a problem? Please describe.
Given the following code:

Chunk :: distinct [CHUNK_SIZE][CHUNK_SIZE]Cube

World :: struct {
    using chunk : Chunk 
}

the compiler gives the error message:

/home/chris/programming/odin/02/main.odin(73:11) Error: 'using' cannot be applied to the field 'chunk' of type 'Chunk'
	using chunk : Chunk

Describe the solution you'd like
I would expect a more detailed error message about how one cannot use the using keyword on arrays
