1329. Recursive deduction substitutions

[Voted into the WP at the February, 2012 meeting; moved to DR at the October, 2012 meeting.]

It is not clear whether the implementation limit on recursion in template instantiation applies only to instantiation itself or also to recursion that occurs during template argument deduction.

Proposed resolution (August, 2011):

Change Clause Annex B [implimits] as follows:

• Recursively nested template instantiations, including substitution during template argument deduction (13.10.3 [temp.deduct]) [1 024].
