When calling
type(<optional>)the expected output would beoptional; however, this failssince the name
optionalis part of the namespace. To ensure optionals are type-testable,the type name has been shifted to
optional_type. This should not break anyone unless youare explicitly querying the type name as part of your implementation.
Additionally, this fix revealed a different issue wherein type identifiers were not being resolved
during type-check unless they were for structured object types. This change introduces a call
to
FindIdentwhich is also the same call being made at runtime to resolve type identifiersduring evaluation.
