That would be awesome. Right now, with Scipy arrays, you get pretty good performance if you use matrix operations and built-in functions. That can be unnatural

That would be awesome. Right now, with Scipy arrays, you get pretty good performance if you use matrix operations and built-in functions. That can be unnatural, besides it would be more efficient to do a plain for loop in an ideal world. Is PyPy optimized for matrix-style code, for loops, or both? What about functional programming, say, finding the maximum of a user-supplied function? Will the maximizing and maximized functions be inlined for performance? Thank you to any answering PyPy developer :)
