The expansion _is_ a string literal.
But one could probably "fake" a pointer-to-member-function, but that
would require the definition of 'Bar' being accessible for further processing
later on, which is, however, not needed in a Qt context, and e.g. Qt Creator's
"weak plugin dependencies" are consciously(!) exploiting this fact.
Of course one could argue that "fringe cases" like that do not have to be
supported by the IDE, but as the IDE itself uses it that's a hard sell ;-}

[... or make "upstream clang" accept the use case as "reasonable".
But even that may pose a challenge...]
