With dmd 2.049 this program:
import std.stdio: writefln;
void main() {
writefln("%d", 1, 2);
}
Prints:
1
But in this case I expect a compile-time error (or equivalent run-time error if
the compiler is lazy and doesn't perform such very basic tests at
compile-time), because the format string doesn't contain the same things as the
given arguments.
In this case printing 12 is not good, because when a writefln is used, it's
better to avoid possible bugs to enforce that arguments and format string match
exactly.
