Just downloaded and installed the latest versions of
BricsCAD (18.1.09) and
DOSLIB (9.03) for same.
Ran a few tests. Absolute speed demon. Generally smokes its rival. The bulk of my utilities work straight out of the can -- and fast! A couple need rework, e.g. MOE (deep dives into the object model), but overall I am seriously impressed with the LISP implementation. VBA based utilities also work (with some re-work to address the lack of the VBASTMT command [or equivalent] so parameter passing from LISP to VBA currently has to be performed via kludgy slight of hand tricks). Anyway ... I'm grinning despite a crushing headache.
Well done Bricsys & partners, kudos!
