Ah, haven't seen this particular version.  It is definitely a lot more flexible.
Although, it is telling that the ClozureCL code base doesn't actually uses the
extra features (which are actually broken, too).  But given the target of
inclusion in Alexandria, flexibility is probably a good thing.

The only thing that irks me is the lack of an implicit return value, although
both features could be provided for by providing a NIL block so that explicit
returns could be used where required.

If folks are more interested in a more general version, I'll put together a
working implementation.
