--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
EDG and MSVC also only reject this when the template is instantiated, only
Clang rejects it when first parsing the template.

I think it would make sense to diagnose this under -Wtemplate-body like other
"this can never be well-formed" bugs in templates.
