Don't agree with everything the author has to say (particularly functions) but I think it's fair criticism.
LightTable isn't going to be a great fit for some languages, specifically c, c#, java and c++ style languages; I'm extremely dubious you'll be able to get the sort 'instant feedback' shown in the demo for that sort of compiled complex language with cyclic dependencies (A imports B imports C, imports A. Yay, java... :P).
...but really, that's not what it's targeting.
So, fair criticism to the author I feel: don't complain you won't be able to use a hammer to cut down a tree.
