In "Lots of low hanging fruit in Phobos" the issue came up about the

Is there any hope of fixing this?
There's nothing to fix.
There is, all right. ElementEncodingType for starters.
Allow me to enumerate the functions of std.algorithm and how they work
today and how they'd work with the proposed change. Let s be a variable
of some string type.
Special case was wrong though - special casing arrays of char[] and
throwing all other ranges of char out the window. The amount of code to
support this schizophrenia is enormous.
Making strings bidirectional ranges has been a very good choice within
the constraints. There was already a string type, and that was
immutable(char)[], and a bunch of code depended on that definition.
Trying to make it work by blowing a hole in the generic range concept
now seems like it wasn't worth it.
