I think most the string functions should be transformative, like 
std.algorithm.map, so they take an input range and return an 
input range.

This lets them chain most easily, letting the user sink them into 
a particular range at the end.


Though we could do a bit of magic to both take an output range 
and return an input range for it (which can also be 
backward-compatible, as we talked about in a thread a month or so 
ago), the most straightforward way is surely to treat it all like 
map.
