Thank you Hervé!

Thank you, again.

A couple more questions while I'm at it, that may expose the limitations in
my understanding of inheritance and project history... 1) Why have some
developers chosen to extend eSet instead of ExpressionSet (definition
and 2) why are these coercion methods developed for ExpressionSet rather
than eSet? Wouldn't an eSet coercion method be preferable because it would
cover ExpressionSet as well as all the classes that extend eSet?
