> Considering how often HOF is used, the impact is huge. Well, yes, that would be the point :) I think I understand what you mean, but I don't see how this is more dangerous/worrying than what is already there. Ok, so (funcall fn (+ 1 2)) may or may not evaluate (+ 1 2). But call-it is already willing to give total control to fn. Will fn call a continuation and never return? Launch nuclear weapons? Giving it additional control over the evaluation of the arguments seems innocent enough.
