It is allowed because the "auto" keyword doesn't actually 
required for auto functions (or variables), what you need is any 
one of the storage classes.

Those include static, auto, const, immutable, even pure.

If any of them are present, the compiler knows you are writing a 
function or declaring a variable and will infer the type.
