Right, that too!

char[] somestring = "....";
func( somestring[0] ); // WRONG: somestring[x] is not 1 character!

Using "string" would make it less obvious:

string somestring = ".....";
func( somestring[0] ); // [0] means what?

This goes for iteration as well. DMD will still deduct 'char' as the 
type type, but at least one's less likely to type foreach(char c;str).

If you want to iterate the UNICODE characters in a string, you'll 
specify "dchar" as the type and you won't worry about "how come I can 
use dchar when it's a char[]":

foreach(dchar c; somestring)
   func(c); // correct
