Putting a type check in + would slow down basic math, and there is a class of user who will complain loudly if basic math slows down.

One approach that's been proposed in #clojure is to make these functions more capable by default, but then provide a fast-math library that could redefine them in terms of numerics-only. I'm a big fan of functions doing the most helpful thing by default but being able to offer better speed when you need it. Convenience vs speed is always a trade-off, but I think convenience should win in the default case. What do others think about this? -Phil --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
