> This is a code style/quality improvement.
> isAssignableFrom is appropriate when the class is not known at compile type, but assignment needs to be checked.
> e.g. foo.getClass().isAssignableFrom(bar.getClass())
> but, if the class of foo is known (e.g. X.class), then instanceof is more appropriate and readable.
> i also made use of de morgan's to simply the "is combininable" boolean statement, which is hard to grok as written.
