Why is that?
import std.stdio, std.array
void main() {
auto output = appender!(string);
output ~= "world!";
// output.data.insertInPlace(0, "Hello, "); // Doesn't work
auto asString = output.data;
asString.insertInPlace(0, "Hello, "); // Works
writeln(asString); // prints "Hello, world!"
}
Error: template std.array.insertInPlace cannot deduce function
