I say this as a huge fan of Lisp and there was a time where it made sense to buy a commercial compiler - that time has passed, because when you buy a compiler and a new language you are also buying into an ecosystem, and the more people that are in that ecosystem the better for you.
I can see maybe using Lisp to do some special parts of the program, but even then there is Chicken Scheme which is free and already have a bunch of eggs (extensions), oh and it compiles to C too.
I for one, think the price tag is reasonable.
You would pay $40 for a T-shirt if it were some sort of collector’s item you could resell. You would pay $100 for running shoes because that’s less than $15000 for knee surgery, and you like having comfy feet. You would pay $150–300 for an ounce of weed because you know what weed is like, and you like it, and the price is driven up by legal issues. But what justification can you come up with for spending $200 on what is essentially a productivity tool, if it won’t necessarily make you more productive?
But book stores, unlike the company that produces mocl, won't give my money back if I find that the book didn't help me within the first 30 days.
So in this case, it's even a relatively safe gamble (assuming of course, that the company does in fact, honor the 30-day money-back thing).
I don't blame you or what you are trying to do, it is the nature of the beast. Introducing a new programming environment is hard enough when it is free, it is nearly impossible when it isn't.
Nowadays there seems to exist a trend developers should work for free.
You do realize this runs Common Lisp, right? There are plenty of Common Lisp libraries.
Don't get me wrong, as a language is it the best that I know of. As an environment, it is not.
Anyway, lispworks seems to be doing fine selling their lisp, so maybe it isn't hopeless for wukix :)
