[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.
