I agree with the point of writing gets more in some cases.
But arange(a, n+1, 0.1) would of course fail in this case.
And the big difference is, that I need to calculate first how many 
steps it is for linspace to achieve what I believe is a frequent user 
case.
As we already have the 'convenience' of both linspace and arange, which 
in principle could be done by one function alone if we'd precalculate 
all required information ourselves, why not go the full way, and take 
all overhead away from the user?
