I would like to throw in one of my favorite functions that I
implemented years ago using (templated) SWIG:

mmms()  calculates min,max,mean and standard deviation in one run.
While - by using SWIG function templates - it can handle multiple
dtypes efficiently (without data copy) I never even attempted to
handle striding or axes...
Similiarly mmm()  ( that is minmaxmean() ) might be also good to have,
if one really needs to not waste the (little?!) extra time of
compiling the sum of the squares (for the std.dev).

I you added this kind of function to the new toolbox, I would be happy
to benchmark it against my venerable (simpler) SWIG version...
