43f3dec00 Remove enum specifier (to avoid re-declare scoped enum as unscoped) (donaloconnor)
Pull request description:
MSVC fails to compile with the changes made in #10742 The problem is enum types were changed to scoped (`enum class`) but in some places `enum` as an unscoped is used. This is a very simple fix and I've tested it. Edit: Had to remove enum altogether - `enum class` doesn't compile on clang.
