People do what is convenient, and as endless experience shows, doing the right 
thing should be easier than doing the wrong thing. If you present people with a 
choice:

#1:    string s;
#2:    immutable(char)[] s;

sure as the sun rises, they will type the former, and it will be subtly 
incorrect if string is const(char)[].

Telling people they should know better and pick #2 instead is a strategy that 
never works very well - not for programming, nor any other endeavor.
