Somewhat off topic, but my main problem with Julia is that my colleagues/correspondents won't understand it, it's not installed anywhere i need it, and my impression is they tried to make it MATLAB'y as though that was a positive rather than a negative.

If I wanted a performant, compiled, solution that allowed me to program up the answer myself that wasn't installed anywhere and everyone else couldn't understand, I'd just cut out the MATLAB syntax and install SBCL lisp :p
