            Bug ID: 190029
           Summary: [WHLSL] Add casts between vector types
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org

There are no cast operators that allow you to cast a vector (or matrix, for that matter) element-wise. For example:

operator int4(uint4 v)
{
    return int4(int(v.x), int(v.y), int(v.z), int(v.w));
}

Metal supports these; I think they would be a useful utility to add to the standard library.
