I should have worded this as:

"People who want arange to return floats *as a default* should be 
directed to linspace"

So, basically, arange is not going to change. 

Because of this, shifting over was a cinch.   I still need to write the 
convert-script code that inserts dtype=int
in routines that use old defaults:  *plea* anybody want to write that??
