using names before they're defined

[Larry Bates]

I don't know if you saw my earlier post but something like
this has worked for me.

What about something like:

supply = supply()
compressor = compressor(supply)
combuster1= combuster(compressor)
combuster2= combuster(compressor)
compressor.append(combuster1)
compressor.append(combuster2)

or perhaps

compressor.extend([combuster1, combuster2])


turbine = turbine(combuster)
combuster.append(turbine)


If you implement .append and .extend methods
on your classes they will allow you to append single
downstream objects or extend with a list of them.
Just keep a list self.downstream and append/extend
it.  IMHO it makes what is going on intuitively obvious.
