Any reason not to make that accurate and return the average of the middle two values for collections containing an even number of items?

One nice thing about the existing definition is that you can use #median on collections that are numeric based.� So, median of:

#( 'Ford' 'Audi' 'Nissan' 'Hyundai' ) median

would actually return in the current definition, but not in a 'statistical' definition.� Similarly, #max and #min and #size�would work for this, although #sum wouldn't.
