Weird outputs of concatenated arrays

Hello,

I'm not sure if it is a bug but how should I understand this?

julia> [[1 1]; 2 ;; 3; [3 4]]
2×3 Matrix{Int64}:
1 3 257641728
2 3 4

Yikes! Since I'm mostly responsible for this feature I can look into it.

Definitely a bug.

This should throw an error. It should be interpreted as equivalent to [[[1 1]; 2] ;; [3 ; [3 4]]]

_typed_hvncat_dims just needs better validation.
