Not likely a speed gain. But it might be nice to have this available for other user-defined material. >> What do people think?

No. They are created by the existing calls of IMPLEMENT_TYPE_P in pitch.cc and duration.cc and initialized there. > Can you use ly_lily_module_constant? It memoizes, so it is efficient. Where is the point? The respective variables _are_ initialized and set with the pristine values of the type checking functions. Memoization can't be faster than that, I should think. It could conceivably make a difference when the user masks the definitions of ly:pitch? or ly:duration? (merely setting them to different values should not be a problem) but that's not really something I want to think about too much. -- David Kastrup _______________________________________________ lilypond-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-devel
