Paul:
When compiled on a 64 bit machine, this line
int r = uniform(0, mobs.length);
".length" returns a size_t, and 0 is an int. uniform() probably
decides to unify those types to a size_t. A size_t is 32 bit on
32 bit machines and 64 bits on 64 bit machines. But D "int" is
always a 32 bit

You didn't assign the result here... the site says
arr = arr.remove(index);
Notice too that the docs do NOT take the array by reference; they
don't necessarily modify it in-place.

There's no guarantee what thread will be used in the standard GC

What about structs? Are the destructors called when they go out
of scope in a C++ RAII fashion, or do they happen on a separate
thread too?

Another possible way is to check the bounds at compile time. The
different operators need to be overloaded for that. For example,
if you have to types Int!(0, 100) and Int!(20, 30), the result
type of an addition needs to be Int!(20, 130).
Then, there can be an overloaded opCast() to bool for

You can't do it directly in D. Someone has to write a packed
