Hi Karl and all,

The relative slowness of high-level languages against C is a known thing beyond Emacs.

Sure, any new C-replacement needs to be checked and also benchmarked. But thats not an action to start with. BTW does anyone still need benchmarks to learn about slowness of propertize and fontification stuff? The whole display-engine IMO is a hot candidate for a thoroughly re-consideration.
