This is an operation I'd like to do:

import std.range, std.algorithm;
void main() {
    auto p = std.array.splitter("this is a message").retro();
}


DMD 2.060alpha gives:

test.d(3): Error: template std.range.retro does not match any function template
declaration
...\dmd2\src\phobos\std\range.d(1292): Error: template std.range.retro(Range)
if (isBidirectionalRange!(Unqual!(Range))) cannot deduce template function from
argument types !()(Result)


I think a splitter of a narrow string can be a BidirectionalRange.
