I see, yes you are right about the price.

I tend to call the attention for these Lisps, just because it seems a large amount of developers aren't aware what they are actually loosing in productivity by sticking with their free (gratis) tools.

Embarcadero is another good example, given what Delphi and C++ Builder were already capable of. Although here they have themselves to blame how Borland lost their hobby market ethos.

What productivity do you gain by using Lispworks? The only benefit is the cross-platofrm graphics api last i checked.

Aside from CAPI, I'd note the excellent platform support (traditionally one would use CCL as a free alternative as SBCL isn't quite there yet) and the possibility to deliver "tiny" executables due to tree shaking.

The class explorer is also excellent for navigating CLOS heavy codebases. Profiler and overall IDE experience is far better for anyone without Emacs Stockholm syndrome (which I do have btw).
