Still, that code cannot be compiled, right?

inout is a wildcard that should be able to take place of const and immutable
but std.array.replace cannot work with const(char)[] nor with
immutable(char)[].

I thought it was supposed to allocate a new array to store the result to?

Seems that way:
http://dlang.org/phobos/std_array.html#replace
Replace occurrences of from with to in subject. Returns a new array without
changing the contents of subject, or the original array if no match is found.

/----
import std.array, std.stdio;

void main()
{
    int[] c = [1, 2, 3];
    c.replace([2], [4, 4]).writeln();      //[1, 4, 4, 3];
    c.writeln();                           //[1, 2, 3];
    c.idup.replace([2], [4, 4]).writeln(); //[1, 4, 4, 3];
}
//----

Ali must be thinking about "replaceInPlace" ?

Sorry for the noise. :( Yes, I thought it was in-place.
