Not sure I understand: how can you be sure a SendSet is in an initializer list?
Or are you using 'initializer' for any kind of variable initialization?

In any case, I think these helper methods belong to the resolver. The helpers
that I would put on a SendSet are get lhs() and get rhs().

Done, moved the helpers.

== -> ===

Also, stringValue is a getter, not a function.

Also, this is dead code. You have two return statements. Did you mean &&?

Done.

How about "onError" instead of "errorHandler"?

Done.
