Overview

Dot3 represents using the ... operator between two expressions. Usually this is to create a range object. It's effectively the same event as the Dot2 node but with this operator you're asking Ruby to omit the final value.

1...2

Like Dot2 it can also be used to create a flip-flop.

if value == 5 ... value == 10
end

One of the sides of the expression may be nil, but not both.
