What's wrong with that returning [1.0, 2.0, ..., 42.0]?  (Well, barring 
round-off error.  The result might be 41.99999 or 41.0000...1)

How hard would it be add an optional step size?  That's a nice feature 
from matlab that I've used a bit, and you often see stuff like 0(.1).9 
in various tables and such.
