GCC verification of printf usage bugs is a hack. It's something
hardcoded into the compiler that only works for printf formats. You
cannot extend it to statically verify other types of formats you might
want to also verify at compile-time.

While writefln can be improved (Andrei has preapproved my enhancement
request to support compile-time format string, for example), there's no
way to make such improvements to GCC's format checking short of
modifying the compiler itself.
