I'm asking mostly because I want to better understand the essence of how clojure works. But you are right in thinking that I am also interested in better understanding performance implications - but this is a secondary reason. Primarily, I'm just trying to understand better. Coming from a C++ background I'm not that familiar with functions as first class values. We sort of do have them in C++ - as functors - ie a class that has the function invocation operator defined. This class can have storage as well, which means you can have a functor object type which then can have particular instances instantiated with different particular parameters stored with the object instance. I'm wondering whether this is effectively what Clojure does under-the-hood, or whether it does something different / more sophisticated. > > As long as the JVM can optimize the procedure, it's of lesser importance > how Clojure solves it in "one-shot" scenarios. > In one sense yes, though it's nice to better understand what is happening and how this influences program performance. > > Maybe I somewhat dodge the question, but dynamic just in time compilation > is so mindblowing cool that an hypothesis about the quickest possible way > to solve the problem combined with profiling is what matters most in > practice. > > /Linus > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
