The same as arange(1, 5, 1j) - an empty array since it takes 0 of the  
step to cross the distance.  But something like
arange(1j, 5j, 1j) seems fine.  As does arange(1j, 3+5j, 2+1j) which  
should give [ 1j, 2+2j ].  The idea is to walk by step up to the edge  
of the box.  I seem to recall a discussion of why this was a bad idea  
a while ago on this list, but I can't find it...

The exception is a good answer too, but it should probably happen for  
all complex arguments, since most seem to return an empty array now.

they're all fine hovses.
