[Moved to DR at the May, 2015 meeting.]
According to 7.5.5 [expr.prim.lambda] paragraph 4,
If a lambda-expression does not include a lambda-declarator, it is as if the lambda-declarator were (). The lambda return type is auto, which is replaced by the trailing-return-type if provided...
trailing-return-type is a syntactic nonterminal that includes the -> and thus cannot be used directly to refer to the type. It should instead say something like, ...the type specified by the trailing-return-type.

Proposed resolution (November, 2014):
Change 7.5.5 [expr.prim.lambda] paragraph 4 as follows:
If a lambda-expression does not include a lambda-declarator, it is as if the lambda-declarator were (). The lambda return type is auto, which is replaced by the trailing-return-type if provided and/or deduced from return statements as described in 126.96.36.199 [dcl.spec.auto]. [Example:...
Change 188.8.131.52 [dcl.fct] paragraph 2 as follows:
The type of the declarator-id in D is “derived-declarator-type-list function of (parameter-declaration-clause) cv-qualifier-seqopt ref-qualifieropt returning
trailing-return-type”. The optional attribute-specifier-seq...
