Hi Viksit, I would suggest that the CL loop construct and the Clojure construct of the same name are, in fact, fairly different beasts, both structurally and in terms of their goals. I don't believe that Rich has any intent to extend loop towards the CL flavored loop. The for construct is more Clojure's answer in that direction, though it is not nearly so flexible.
No reason you couldn't build something similar to CL's loop construct in Clojure, but Clojurians in general seem to have an aversion to its "boil the ocean" nature. I do think, however, that it would be nice to have some syntactic sugar for consuming sequences in parallel in the for construct. I can't think of a nice way to do it right now, though.
