This raises a different question with me... Does clojure have the same scope for code optimization that other languages, eg C++, have? Ie, even though a C++ compiler has to deal with all sorts of complicated syntax, it is able to perform a whole lot of at-compile-time optimizations based on the C++ semantics. Is the clojure compiler free to do a similar thing? Or is it bound to adhere to the straightforward evaluation rules? My understanding is that one of the roles of macros is to perform at-compile-time optimizations. Sometimes a macro can do something clever to transform less performant code into optimized code. But is this the only way of improving compiled code - ie introducing code-optimizing macros - or does the clojure compiler itself have scope to elide certain things and make other performance optimizations? I know the java JIT optimization reduces the need for this, but my guess is that there is still a role for at-compile-time code optimization.
