Number of compiler passes does not reflect its "complexity". Can in fact be the opposite - the more distinct passes there are, the simpler each of the passes is, together making the whole thing simpler. > Clojure being the obvious one Clojure, to be honest, is an example of a very convoluted, not very well thought out compiler design. Disclaimer: I know nothing about the actual Scala compiler passes, just commenting on the number of passes as a proxy for complexity.
