  The design of the macros requires a type to be provided to the macro.

By expanding the type parameter inside of typeof it also inadvertently
allows an expression to be used which appears not to have been intended
after evaluating the parameter name and existing macro use.

Technically this is an API break but only for applications that were
using these macros outside of the original design intent.
