I could not find any examples dealing with (custom) variable resolvers.
How are custom variable resolvers implemented and registered to be used in
the evaluation context/service?

An evaluation context can be created with an IVariableResolver and used
programmaticly with core expressions. There is no support, however, to
contribute a custom resolver to the IEvaluationService at this time.

I was exploring this for dynamic variables:
