A CPAN::Meta::Requirements object models a set of version constraints
like those specified in the META.yml or META.json files in CPAN
distributions, and as defined by CPAN::Meta::Spec. It can be built
up by adding more and more constraints, and it will reduce them to
the simplest representation.

Logically impossible constraints will be identified immediately by
thrown exceptions.
