Comparison operator overloading

[Márcio Martins via Digitalmars-d-learn]

I am writing a generic numerical array struct, and I can't find a 
way to do element-wise comparison operators.

What I had envisioned was something like the following, assuming 
a, b, c and m are array-like, and all operations return arrays.

auto m = (a > b) * a + 15;
auto c = a.choose(a > b)^^2;

However, it seems this can't be achieved at the moment, as far as 
I can tell.

The rewriting of a >= b to a.opCmp(b) >= 0 seems limiting in the 
sense that it assumes scalar-like operands and semantics, which 
is surprising, and goes against the awesome flexibility of the 
remaining operator overloads.

Tried to look around, but according to google, the only reference 
I have seen to this was someone with a similar question in 2004, 
which is surprising to say the least. I suppose either I am 
missing something really obvious, or I am out of luck?
