--- Comment #21 from Jens Gustedt <jens.gustedt at inria dot fr> --- I would be much happier with a generic operator that makes any object into an rvalue. One way that comes close would be `1 ? (X) : (X)`. This is an expression that transforms any expression `X` that is not a narrow integer type into an rvalue. Unfortunately it is too ugly that anybody ever will systematically write `__typeof__(1?(X):(X))`. But a macro #define __typeof_unqual__(X) __typeof__(1?(X):(X)) could do. (And one could fix the finite number of cases that are not covered with `_Generic`.) I'd like to have prefix `+` for that. This could be useful in `__typeof__` but also in `_Generic`. Maybe gcc could extend that operator to be applicable to all types.
