Please demonstrate a few.  And persistence is not an application
requirement, it's an architectural issue.  Name places in business
applications where inheritance works better than composition.

None of those languages is any good for business logic, though.

Also, your statement depends on what you consider a language.  ILE RPG
is all but a completely new language, and it does not have inheritance.

And in any case, the point is not whether inheritance is good or bad,
but whether it is appropriate for business programming.  My position is
that it is not, and that except for the most trivial applications I can
write business logic much more quickly and flexibly in RPG than any
other language.
