Oh dear.. you won't like the project manager backend I'm writing for
scripting gsch2pcb updates to a running copy of PCB. Its in Python and
(mis)uses generator functions to implement a less than obvious program
flow. It writes out to PCB, then the generator function yields, until an
IO callback causes it to re-enter where it left off.

Its quite an elegant way to do it in some respects, and saves a complete
state-machine implementation for every action I request PCB to do (which
needs a response). Will require a little documentation.
