1389. Recursive reference in trailing-return-type

Section: 9.3.4.6  [dcl.fct]     Status: NAD     Submitter: Daniel Krügler     Date: 2011-09-04

There doesn't appear to be an explicit prohibition of a function declaration of the form

    auto f() -> decltype(f());

Presumably there should be.

Rationale (February, 2012):

As noted in issue 1433, the point of declaration of the function name is after the complete declarator, i.e., after the trailing return type, so the recursion posited in this issue cannot occur.
