I am sort of OK with this as far as it goes, but had not thought that
we should depend on names so much.  That is, the rules I had in mind
were more along the lines of

  A step with only one unspecified input, preceded or within a
  step/container with only one port available for binding, defaults to
  that input being piped from that port

But that doesn't manage the defaulting of the pipeline to the first
step very well in many cases, including your example. . .

My earlier suggestions about this had depended on a notion of
'primary' inputs and outputs. . .  But no such notion is currently
defined.  I feel like it might be useful in other ways. . .

Hmm.  We do after all _control_ the names of all the built-in
components. . .
