It's definitely an interesting area to tinker with.

Yes, for small languages they do work well. How well such an approach
scales to a full sized language (of any sort) is much less clear. I am
also curious about the extent to which the functional paradigm can be
used to simplify(?) compiler implementation. Scala, like many functional
languages has nice pattern matching features that seem to be useful but
that is just a small matter in the grand scheme of functional programming.

It is easy to understand why. I intend to work around this issue by just
redefining "success." Of course my definition might not be very
interesting to most people... but that's fine.
