Because it would always interpret a list of values as a single item.
This function looks at args and if its a single value without an "__iter__"
method, it passes it to min as min([value], **kwds) instead of min(value,
Another way to do this would be to use a try-except...
return min(*args, **kwds)
return min(args, **kwds)
