The main goal was to make it possible to give generic functions definitions (since the code would be very dependent on the actual parameter types), but will also allow for inline functions. It also helped move a lot of the back-end dependent code out of semantics processing and almost completely (if not completely) out of the parser. Possibly more importantly, it gets the dags flushing out of the parser, which means such is now shared by all front-ends. There's probably a lot of dead code in expr.c now, but that can be taken care of another time.
