1160. Definitions of template members and the current instantiation

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

The current rules for determining whether a name refers to the current instantiation, given in 13.8.3.2 [temp.dep.type] paragraph 1, do not cover the case when a template-id matching a primary template or partial specialization appears in the definition of a member of the template.

Proposed resolution (August, 2010):

Change 13.8.3.2 [temp.dep.type] paragraph 1 as follows:

In the definition of a class template, a nested class of a class template, a member of a class template, or a member of a nested class of a class template, a A name refers to the current instantiation if it is

• in the definition of a class template, a nested class of a class template, a member of a class template, or a member of a nested class of a class template, the injected-class-name (Clause 11 [class]) of the class template or nested class,

• in the definition of a primary class template or a member of a primary class template, the name of the class template followed by the template argument list of the primary template (as described below) enclosed in <>,

• in the definition of a nested class of a class template, the name of the nested class referenced as a member of the current instantiation, or

• in the definition of a partial specialization or a member of a partial specialization, the name of the class template followed by the template argument list of the partial specialization enclosed in <>. If the nth template parameter is a parameter pack, the nth template argument is a pack expansion (13.7.4 [temp.variadic]) whose pattern is the name of the parameter pack.
