--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed; EDG accepts it also in C++17 (and C++20) modes.=20

Also note If I change slice_by_type to take Bar instead of the template
argument, it works which makes it feel like for some reason GCC is not able=
 to
deduce the arguments properly.=
