Hi Thiago,

In clang’s AST, hidden friends are placed like class member functions, so they have to be documented like class members, e.g.

\fn int QMetaType::qRegisterMetaType(QMetaType meta)

This is misleading in this case, and outright invalid C++ in case of operators as hidden friends, but it works with the latter, and I expect it will make it work with this as well.
