Gaps in the reflective type system are bugs, but they are not showstopper bugs. We do not even expose any way to query the reflective system today; it basically only affects type equality and dynamic casts that programmers are very unlikely to use. The changes in call type-checking are vastly more important, are implemented (modulo bugs, of course), and by themselves warrant calling SE-0110 implemented. John. > > And yet: > > 1.
