> Does the struct consume any space when compiled? Or is it acting like a class here and declaring a scoped enum within itself?  
It only declares the value for the enum, so it shoudn't consume any space, but I'm not 100% sure.

> I tend to prefer type-safe code over macros as long as there aren't any bad side-effects to using it.  :)
Because the macro uses a template function it's typesafe too. It throws a compiler error when used with wrong type (e.g. char*).
IMHO ARRAY_LEGTH(tokens) is easier to read compared to array_info<tokens>::size.
