- Value Params
- path
the unresolved path
- Returns

Returns a new resolver that falls back to the given resolver if this one doesn't provide a substitution itself.
Returns a new resolver that falls back to the given resolver if this one doesn't provide a substitution itself.
It's important to handle the case where you already have the fallback with a "return this", i.e. this method should not create a new object if the fallback is the same one you already have. The same fallback may be added repeatedly.
