Yes, there is a way to do it: ensure default rounding mode is set and call
`rint`. But there is still two function calls (i.e. one
`with(FloatingPointControl) assert(rounding == roundToNearest)`) if you control
rounding mode and even more calls if you don't.

My point is: why are we using C behavior for `round` when it is not a generally
wanted behaviour? It's like keeping C issues in D and I don't see any point of
it.
