When my function will be a lot slower if you pass in a heterogeneous array, 
and I want to avoid programmers accidentally and obliviously doing that. 
Now, I could convert heterogeneous arrays to homogeneous ones within the 
function, but the Julia style 
guide<http://julia.readthedocs.org/en/latest/manual/style-guide/#handle-excess-argument-diversity-in-the-caller>very
 sensibly counsels against that.
