Description

24.6.2 "static foreach supports multiple variables in cases where the corresponding foreach statement supports them. (In this case, static foreach generates a compile-time sequence of tuples, and the tuples are subsequently unpacked during iteration)."

I do not understand these phrases. Please rewrite this specification fragment to be understandable.

What does it mean "foreach statement supports multiple variables"?
