Are you looking for something like int_fast32_t and the likes
from Boost? If you don't care terribly much for when your numbers
overflow, then as others suggested, size_t and pttwhatever work
fine.

You mean a random seed? Once seeded, you shouldn't have to
re-seed a PRNG: It'll generate random numbers forever. Or do
you mean "re-seed" in the sense "reset"? Becau

I've noticed that const(char)** can be accessed via indexes:

cool!
This is a feature that works with all pointers to a sequence of
items, like in C. But array bounds are not verified, so it's more
bug-prone. So if you know the leng

If you know that you have N strings, then a solution is
(untested):
pp[0 .. N].map!text.array
If it doesn't work, try:
pp[0 .. N].map!(to!string).

I'd also suggest the following alternative, if you're going to
discard a lot of last elements in your code:

auto poppedBack (T) (T seq) if (isInputRange!T) {

You are going to need the length of your c char*[] then a

From your error message: isForwardRange!Separator
Your separator is a character, which isn't a forward range.
Try this:
`auto name1 = joiner(nameparts[0 .. $-1], ".");`
But splitting on a char is a common operation
