IIUC, this is just standard Python syntax for expanding a list into 
positional parameters when calling a callable.  Because the syntax 
requires calling a callable, it won't work for the a=*array(...) 
tries.   To get it to work when specifying extent, do 
"quiver3d(extent=(..), *array(...)) -- * expansion must be after any 
normal positional parameters and keyword values.
