Very true.

My favorite example is the notion of "purity" of OO languages, which
holds that some good comes from the ability to say "everything is a
class".  The only result is that you have to contort everything into
_being_ a class for the sake of being able to say this, so for instance
you have to have a "singleton" design pattern to work around not having
packages with state, etc.
