Watch out though: The compiler will compile a different function per set
of values. For example, there will be separate RandomChoice instances
for ("hello") vs. ("world").
D has a simple variadic parameter syntax as well:
auto RandomChoice(R)(R[] r...)

Which makes that simpler as well because being a slice, r is already a
range. And there is choice():
return r.choice(rnd);
Something is very important though: The 'r' slice is short-lived; it
does not live in dynamic memory. RandomChoice() should not save it for
later use nor return it. (The compiler may have protection against that;
I am not sure.)
