simd comparison operator?

Are there any plans that would allow using opEqual or opCmp
operators with simd?
My use case is that I have arrays, and I need to verify that ALL
the elements in my array are comprised between two values (in
this specific case 10 and 93).
I was hoping I would be able to use:
ubyte[] arr = ...
if (arr []< 10 || arr[]> 93) throw Exception();
But that doesn't seem to work.
Neither does simple opEqual comparison.
//Make sure arr is initialized to 0
if (arr[] != 0)
Is this a "never thought of this and not implemented" issue, or
is there a reason that simd can't do this? I find it strange,
since simd allows for straight up array to array opEquals, but
not array to value?
--------
Anybody have any idea as a workaround? My program has very high
data throughput, and never actually handles the array elements
individually, just manipulates them simd chunks at once.
Validating the content is important, but performance is taking a
real toll...
