The omission of dchar is on purpose.  Phobos has characterized string as a  
bidirectional range of dchars.  For every range where I do:

foreach(e; range)

e is of the type of the range.  Except for char and wchar.  This  
schizophrenia of type induction is very bad for D, and it's a good  
argument of why strings should not simply be arrays.
