Hey,
I am trying to generate an array of 10 unique (!) random numbers
from 1 to 1000 each (for example). The best I could come up with
is:
auto arr = iota(1, 1000).array;
randomShuffle(arr);
return arr.take(10).array.sort;
This leaves me quite unhappy, because I would like the code

If it's not obvious, you should terminate the runtime as well when your
program ends. There's a corresponding function for that.

Surely. :-)

This is a solution, but it's not nice:

In D there is no C++ friend nor classes split as in C#. D Classes

Because the runtime is not written in D. :) However, it should be easy

Again, this seems like an unimportant technicality.
For user code, whether the logic is handled in the compiler or druntime
shouldn't make a difference, so why not have version(D_NoBoundsChecks)
instead of version(noboundscheck). It makes it more discoverable, and more
consistent with the rest
I meant 'why not have version(noboundscheck) instead of

whether the logic is done in compiler or druntime shouldn't matter to user,
so it'd be nice to use as uniform syntax as possible, ie:

Implementation can then use that version flag to set compiler
