e.g. what reasoning is the opening poster referring to? What does he mean by reach? And what exactly is the ellipsis covering up?
That's what I was trying to suggest, although you worded it better.


Specifically:

x < y < z is a mild form of 'abuse of notation' as it's called.
So let's agree that x < y < z to mean x < y /\ y < z, x < y < z < a to mean x < y /\ y < z /\ z < a ...

where I am using the ... to mean something similar to the meaning of the ... that the OP was asking about in the first place
