[dcl.decl] p5 says

The type-id in a trailing-return-type includes the longest possible sequence of _abstract-declarator_s.

However, the grammar of trailing-return-type (which is " -> trailing-type-specifier-seq abstract-declaratoropt") does not contain a type-id.

Moreover, I cannot find any ambiguity in the accompanying example. Perhaps this disambiguation rule is no longer necessary after the adoption of CWG 681.

I agree that both the normative text and the example are wrong. It does look like the disambiguation rule is no longer needed, but removing a normative rule (even one that we believe has no effect) is non-editorial. I'll forward this to CWG.

Fixed by CWG 2040.
