I'm just worried about casts because I read somewhere that 
strings start with the number of characters inside them (probably 
in slices documentation), and not with actual content (though 
string literals probably act different in this case).

Documentation on casts say:

Casting a pointer type to and from a class type is done as a type 
paint (i.e. a reinterpret cast).

Reinterpretation is rather dangerous if strings are stored 

But this test gives me a good hope on this case:

     writeln(*(cast(char*) "Test"));

Casting is what I'm going with. .dup.ptr is less clear in this
