Yes, but in comparisons of evaluators it was always held against it. And admitted, if it comes precompiled with FPC, it is kind of limiting. So I'm current implementing this.

Yes, fast eval for graphs, mine too. But I limit myself to work without assembler because FPC is portable.

Yes, unary minus is handled properly. I also try to return a position where a parser fault surfaces if possible.
