Can be made to work without autodecoding.
By special casing? Perhaps.
The argument to canFind() can be detected as not being a char, then decoded into
a sequence of char's, then forwarded to a substring search.
I seem to recall though that one major issue with
autodecoding was that it special-cases certain algorithms. So you'd need to go
through all of std.algorithm and make sure you can special-case your way out of
situations that work today.
That's right. A side effect of that is that the algorithms will go even faster!
So it's good.
(A substring of codeunits is faster to search than decoding the input stream.)
