Agreed :)

Ah, thanks for pointing that out.  Unfortunately, all three of his
proposals were incompatible with SRFI-45, and were not adopted anywhere
as far as I can tell (not in Racket at least).  His least incompatible
proposal changed 'eager' into a macro, so that it could accept a single
expression that returns multiple values.

It's too bad no one proposed supporting multiple values before SRFI-45
was finalized.  As it is, this is the best we can do while remaining
compatible with SRFI-45.

    Thanks,
      Mark
