no, pointer to the actual function is stored in a per-type (not per-object) table, the object stores a single pointer to the per-type function table, and that pointer is needed anyway for a type with virtual members. (btw I thought without checking that to_string is inherited from a (very low level) base and now I can't easily check whether it's really so - is it?) p _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
