Is it even possible to compile D for iOS and use it the same
way as compiled C++ static library? (We do need a D runtime)
Yes, druntime/Phobos will need to be linked like any other static
library.

String **literals** have a terminating null character, to help

What is the difference between -O2 and -O3 ldc2 compiler optimizations?
`--help` says -O2 is "Good optimizations" and -O3 "Aggressive
optimizations". Not very specific.

Is it possible to retrieve also the caller return type? Something like:
Yes, kind of:

In general, if you want to parallelize something, you should aim to have
as many threads as you have cores.
That should be _logical_ cores. If the CPU supports hyper threading it
can run two threads per core.

You have not enabled optimizations. You should compile with `-O -release
-inline` to enable all optimizations.
Without optimizations I get numbers like these:
