> Ack, the example is bad. This one generates rol/ror:

For normal D programmers it's easy to write D "rotation" code that the D
compiler doesn't recognize. So here I have proposed to add two standard rol/ror
template functions to core.bitop that all D programmers can use safely and all
D compilers can optimize well.
