import std.stdio: writefln;
import std.typecons: Tuple;
void main() {
    writefln("%f", (Tuple!(int)).init);
}


Compiled with DMD 2.049 prints at runtime:
Prints: Tuple!(int)(0)

But I expect a compile-time error for the mismatch of the format string (and if
that's not possible because the D compiler doesn't perform this basic test at
compile-time, at run-time).

writefln() probably needs more unittests.
