Error: template std.utf.decode cannot deduce function from
argument types !()(string, int), candidates are:
D:\msc\D\dmd2\windows\bin\..\..\src\phobos\std\utf.d(924):
std.utf.decode(S)(auto ref S str, ref size_t index) if
(!isSomeString!S && isRandomAccessRange!S && hasSlicing!S &&

D:\msc\D\dmd2\windows\bin\..\..\src\phobos\std\utf.d(942):
std.utf.decode(S)(auto ref S str, ref size_t index) if
(isSomeString!S)
why doesn't "decode(S)(auto ref S str, ref size_t index) if
(isSomeString!S)" correspond?
rvalues cannot be ref it seems
Yes. Interestingly, in D rvalues cannot be bound even to const ref.
void main()
{
import std.stdio;
import std.utf;
size_t index = 1;
dchar decoded = decode("dlang", index);
writefln("decoded '%s', next character is at index %s.",
decoded, index);
}
The output:
decoded 'l', next character is at index 2.
