Do you guys know if anybody has done any CAM work in Racket, Scheme, Lisp, etc.? Perhaps one of these 30-day wonders from the PLTgames contest. :-) </span><span style="font-size: 12pt; background-color: transparent;">Actually, I'd be interested in hearing about any language used as a framework for CAM (I have no patience for point-and-click CAM software, but I'm only interested in DSL CAM systems).</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span><br></span></div><div

I'm still interested in Scheme/Racket, but I can't think of any practical use for it at this time.</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span><br></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span style="background-color: transparent;">I would be very dubious of using Racket to implement a DSL. Racket seems too complicated for most non-programmers to learn, and a DSL is supposedly for non-programmers to use (machinists are intelligent people, but there is a reason why they became machinists
rather than programmers --- they just aren't interested in computer science). Also, most DSLs will need a custom data type, which implies that assembly-language is needed. </span><span style="background-color: transparent;">What exactly does Racket or Scheme offer in regard to implementing a DSL? </span><span style="background-color: transparent;">I admit that I don't know much about Racket or Scheme. These languages are supposed to be good for DSL implementation though, and I'm totally not getting why I would want to use them rather than good old assembly-language.</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0);
