detecting sealed objects

# Neil Mix (19 years ago)

I don't see anything in the intrinsic::NominalType interface that
allows one to detect whether or not an object is sealed. Is there
some way to detect that?

Also, in the meta-objects proposal, I'm wondering why indicators for
dynamic/final/internal/public aren't available via ClassType -- is
that a burden on implementors?

Good catch. There needs to be flag on what we are now calling InstanceType to tell the static type checking to skip unresolved reference errors.
