Given a string
string input = "rgb:20/30/40";
And the following:
ubyte r, g, b;
auto numRead = formattedRead(dropExactly(input, 4),
"%x/%x/%x", &r, &g, &b); // does not compile
auto numRead = formattedRead(input[4..$], "%x/%x/%x", &r,
&g,
&b); // does not compile
string s2 = input[4..$];
auto numRead = formattedRead(s2, "%x/%x/%x", &r, &g, &b);
// compiles
Why do the first two fail to compile but the last one does?! I
cannot see any difference between the 's2' case and the second
case, it is a completely mechanical source code transformation I
have made.
