If you want to check that assigned values are valid at the
time of assignment (instead of later during validation),
please consider using "typed_attr" from my "chattr" gem.

gem install chattr

class Foo
	typed_attr String :bar do |v| v.size <= 20 end
end

Now you can't assign a string that's nil or more than 20 characters
without an exception being thrown.
