What does 'fby' mean?

  I _think_ (but unsure) that it should be read “followed by”, and only makes sense in the context of a while loop, where `x = y fby z` means that x will take the value of y on the first iteration and z on subsequent iterations.

    You're right, the name was borrowed from Lucid, where it is a proper operator on streams.
