I think this is a key issue here: multi-clause funs just don't happen all
that often.  It was very late in my Erlang learning experience that I found
the need for multi-clause funs, and I easily found the documentation at the
time.  I did notice the syntax inconsistency, but didn't care.   Anyway, it
is often a good idea to break funs out into full functions to reduce nesting
and facilitate tracing.  Lots of funs make programs hard to debug.
