Well, using the string alias leads to problems, esp. when used as a 
function parameter:
int func(string str)

This makes it impossible to pass a mutable string to the function in D2.

I personally use an  alias const(char)[] cstring;  for most of my 
parameters and  alias invariant(char)[] istring;  for normal immutable 
strings.
