There was a problem hiding this comment.
This change makes it sound like it's OK to use extern with a class member or function parameter so long as there's no initializer. Moving the "block-scope variable with an initializer" case to the start of the list would help.

The current specification lives in [dcl.init], but it fits better in the specification of
extern, since the only way a local variable can acquire external or internal linkage is through the use ofextern, and it's better to specify such broad restrictions in one place.
