Jens Maurer <jens.maurer at gmx dot net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jens.maurer at gmx dot net --- Comment #3 from Jens Maurer <jens.maurer at gmx dot net> --- Note that the ref-qualified function type is not directly an argument for a template type parameter (which would be allowed), but it's a function parameter type inside a function declarator. And those do decay to (possibly ill-formed) pointers.
