Clang has this nice feature that it will warn you when you

With the CTFE power of D, we should be able to do the same
thing when the format string is available at compile time.
Instead of throwing exceptions at run time.
I thought LDC already did that when `-check-printf-calls` is
passed, but the implementation is unfinished and it does not do
any checking at the moment.
