Is std.array.replace supposed to work with char[]?

I use this thread to ask regarding one specific little problem I have with strings. I want to generate a random string of AB using the array, map, etc, this looks like a possible implementation (in std.random there is no choice() function yet):


import std.stdio, std.random, std.string, std.algorithm, std.range;
void main() {
    auto m = map!((i){ return "AB"[uniform(0,2)]; })(iota(10));
    string s = join(array(m));
    writeln(s);
}


It gives this error:
...\dmd\src\phobos\std\array.d(62): Error: result[i] isn't mutable
test.d(5): Error: template instance std.array.array!(Map!(__dgliteral1,Iota!(int,uint))) error instantiating

What's the right way to write it in D?

The same code in Python2.x:

from random import choice
s = "".join(choice("AB") for _ in xrange(10))
print s
