[Voted into WP at March, 2010 meeting.]

Proposed resolution (October, 2009):

1. Change 6.1 [basic.pre] paragraph 3 as follows:

An entity is a value, object, variable, reference, function, enumerator, type, class member, template, template specialization, namespace, or parameter pack, or this.

For the purpose of describing the behavior of lambda-expressions below, this is considered to be “used” if replacing this by an invented variable v with automatic storage duration and the same type as this would result in v being used (6.3 [basic.def.odr]).

At least in the new wording for 7.5.5 [expr.prim.lambda] paragraph 10 as found in paper N2927, this is explicitly assumed to be an entity. It should be investigated whether this should be added to the list of entities found in 6.1 [basic.pre] paragraph 3.
