Looks very promising. One question though, why not use
std.datetime.stopwatch.benchmark? I think it has some
protection against optimizing compilers (I may be wrong
though). Also, LDC has attributes to control optimizations on
a per function basis.see :
https://wiki.dlang.org/LDC-specific_language_changes
Unfortunately, std.datetime.stopwatch.benchmark does not yet
have such protections. It has been discussed, but there were
issues with it that still need to be sorted out.
In any case, what he has implemented is pretty much what's in
Phobos except for the fact that he set up his to take
arguments, whereas Phobos' solution just takes the function(s)
to call, so anything that it does has to be self-contained.

huh. I saw the PR and assumed it was accepted. Anyway, for DMD
putting `asm` blocks seems to still disable optimizations, and
for LDC, the pragma is perfect. GDC is the only unknown.
