[Voted into the WP at the November, 2010 meeting.]

Proposed resolution (August, 2010):

Change 13.4.3 [temp.arg.nontype] bullet 1.3 as follows:

• the address of an object with static storage duration and external or internal linkage or a function with external or internal linkage, including function templates...

This resolution also resolves issue 1154.

Now that local classes can be used as template arguments, it seems odd that there are “external linkage” restrictions on non-type template parameters. The addresses of objects and functions with internal linkage should be permitted as well.
