I can't find any traits `hasIndexing!R` corresponding to `std.range.primitives.hasSlicing!R`

that is `true` iff `R` has `opIndex[size_t]` defined. Is there one?

If not what should I use instead?

My definition of `hasIndexing` so far:

The traits in std.range are specifically for ranges, and isRandomAccessRange already covers indexing, which is why there isn't a separate trait for indexing in there. There certainly _could_ be one in std.traits, but there isn't at present.
