The slides are great. Many thanks for sharing. I do have a question about macros that maybe you can answer. In your nb on metaprogramming you have the horner macro listed and it uses a temporary variable t. But this macro can be written without using a temporary variable. It turns out to be slower (the no temp version) if we are computing a bunch of polynomials with the same coefficients, but is a tiny bit faster if the coefficients are always changing. So are the Expr's cached? Or is something else going on?
Also (OK I have two questions) it looks like we cannot splice into a macro call? Ie @mymacro(x, y...) doesn't work? Thanks again. Don On Friday, August 29, 2014 4:08:44 AM UTC-7, Steven G.
