--- Comment #1 from Timothee Cour <timothee.cour2 at gmail.com> ---
NOTE:
for context here's the enum:
```
enum SliceKind
{
    /// A slice has strides for all dimensions.
    universal,
    /// A slice has >=2 dimensions and row dimension is contiguous.
    canonical,
    /// A slice is a flat contiguous data without strides.
    contiguous,
}
```

I'd expect to see:
s/cast(SliceKind)2/contiguous or even better, SliceKind.contiguous
