The discussion will be started at the end of this year in comp.cad.autocad with chosing a 3-5 people committee which should decide about names and features. Till this date I will provide a first draft first discussed in the committee, then after the fixes a second draft for public discussion. It would be I good idea if it could be packaged with the next release or the next bugfix, unsupported as the bonus utilities. A first pre-draft is already available as Windows Helpfile, but need to be revised before public discussion. Don't ask for it yet.
Contributors are always welcome.
The implementations of the presented functions are not solid as rock, just examples how I implemented them in the last 5 years. As I saw with the writing of the comp.cad.autocad AutoLISP FAQ there were a lot of bugs, even in functions I used for years without any problem, and then from rewriting to a better style. Common argument names and so on. Only the definitions, return values and side-effects should be defined very strict. Of course everybody may and do define its own function implementations, but some will be spread as protected or compiled versions or even be built-in in future releases of AutoLISP or Vital Lisp .
