Mikhail Glukhikh 9ef89447b3 Sealed sub-class -> object: handle equals, suggest "add equals"
Before this commit, sealed sub-class without state was considered
a style issue.
After this commit, sealed sub-class without state AND custom equals
is considered a probable bug,
because comparison of its instances is very fragile.
Alternative fix (generate equals & hashCode by identity) is added.
