There's also the shuffle module in mach.range which doesn't do
any auto-decoding:

Interesting project. Thanks for the link.

If you are absolutely, 100% certain that you are dealing with

That will give you a ubyte[] for char[] and a ushort[] for

I'm trying to shuffle a character array but I get some

OMG! I'm so blind.
Never thought of trying the obvious way.
Thank you
Thank you!
That clarified a lot of things for me.
Hi,
I'm trying the following code:
class counter

I get the following error from the compiler:

or if you know that the string is always going to just contain

Thank you both for the very good insights. Community wise +1 :)
Thank you for the example.
I misunderstood the doc and I got a bit confused by the range -
in C++ I would have incremented the iterators but here I did not
know what to do exactly as I could not match the 2 different
concepts in functionality.

Hi,
I am trying to use the function "mismatch" from
std.algorithm.comparison like so:
int count = 0;
auto m = mismatch(lhs, rhs);
while (!m[0].empty)
{
++count;
m = mismatch(m[0], m[1]);
}
That goes into an infinite loop. What does mismatch return when
