Suppose I want to calculate function values across a continuous interval. 
Obviously an elegant way of doing this is to foreach across the range of an iota 
that covers the interval with small increment.

However, the function may be asymptotic at either the upper or lower boundary, 
or both, or none.  So I need to be able to indicate correspondingly whether the 
upper or lower bounds of the iota should be included or not.

It's maybe not the most important use-case, but if the change can be introduced 
in a non-breaking way, why not?
