[Accepted at the November, 2020 meeting as part of paper P1787R6 and moved to DR at the February, 2021 meeting.]
The “Down with typename!” paper, P0634R3, overlooked the case of a conversion-type-id in a conversion-function-id:
template<class T> struct S { operator typename T::X(); // typename is not helpful here. };
This context should be added to the list of contexts in which a qualified-id is assumed to name a type.
