It would be very helpful to implement isequal and hash in a fast efficient manner since in many uses Element instances are used as keys.

For example: Base.hash(elm::Element) = hash(elm.number) Base.isequal(elm1::Element,elm2::Element) = elm1.number==elm2.number

and maybe also

Base.isless(elm1::Element, elm2::Element) = elm1.number < elm2.number

A PR would be welcome.
