Can you be more clear? I think you got the two examples mixed up.
Also, the second example compiles with wchar and char, not just dchar, and the
following works:
```d
void main()
{
wchar[] a = "ab"w.dup;
wchar[]b = a.dup;
import std.stdio;
writeln("Type of a[0 .. $-1]: ", typeof(a[0 .. $-1]).stringof);
writeln("Type of b[1 .. $].idup: ", typeof(b[1 .. $].idup).stringof);
a[0 .. $-1] = b[1 .. $].idup; //See? Two completely different arrays.
--a.length;
writeln(a);
writeln(typeof(a).stringof);
}
```
This is assigning an array of immutable wchars to an array of mutable wchars.
No matter how you put it, this is a violation of the type system.
