Re: Compile time format string check

[Richard (Rikki) Andrew Cattermole via Digitalmars-d-learn]

If its a string literal it is already handled as part of bindings: 
https://dlang.org/spec/pragma.html#printf

I understand that you may be wanting a runtime error, but I'd suggest 
disallowing that entirely and go with a template parameter to provide 
your format to make sure its seeable to the compiler.
