I was actually expecting one of the Ruby people to pipe up about this; I
think their closure-like things would handle this rather more
elegantly.

2.3 is supported, and will remain so until there is a really strong

number of people using it.

At the moment the test suite needs 2.4 but I see that as a bug.
