Fewer keystrokes... :-)


There is a slightly better reason in that you might have an
extern decl in an included file and by just using .* in the
file containing the declaration, you can guarantee consistency.
Of course, given implicit nets, you can easily argue the dangers of
just picking up such changes and that it might be better to have the
redundancy as a check on the sanity of the module; I'd be on that side
of the argument.  But obviously not everyone agrees.

I am no fan of extern modules at all; the arguments in favor
have never seemed compelling to me.
