@Endilll I tried to follow the existing "naming convention" used in other
diagnostics to strike a balance between being correct & comprehensible for
users. Removing "elaborated" isn't quite correct because an enumeration type
_can_ be a friend (e.g. `enum class E; struct A { friend E; };`; such a
declaration is ignored) -- you just can't declare a friend using an
elaborated-type-specifier starting with `enum` (i.e. `friend enum E`).
Here is an alternative if you think changing this is necessary:
