Black-box the BuilderImpl by putting the BuilderImpl into the from_program.cc file. Why: * It means there's only a single definition of all the methods that need to be maintained, instead of pointlessly splitting code between two files (.cc / .h). * It removes all the implementation details from the header. * It removes a whole bunch of transitive includes, slowing compiles. * It prevents the temptation for future #includes to private-implementation details. * It reduces the amount of symbols declared outside of anonymous namespaces, reducing symbol polution and the amount of work on the linker.
