5. Implement new std.array.front for strings that doesn't decode.
Until then, how will people use strings with algorithms when they mean
to use them per-byte? A .raw property which casts to ubyte[]?
There's no "until then".
A current ".representation" property already exists that casts all
string types appropriately.
There is however a big glaring failure: std.algorithm specialized for
char[], wchar[] but not for any RandomAccessRange!char or
RandomAccessRange!wchar.
So if I for instance get a custom slice type (e.g. a ring buffer), then
I'm out of luck w/o both "auto-magic dchar range" and special code in
std.algo that works with chars as code units.
If there is a way to exploit the duality of RA range of code units being
"is a" BD range of code points we certainly have failed with making it
work (first of all doing horrible job at generic-ness as mentioned).
