Clearly, nirvana is continuous compilation, where the compiler
performs explicit dependency management at the level of nodes
in the syntax tree.
Yeah I was wondering if we can merge some of rdmd functionality
into compiler to speed up rebuilds and do better dependency
tracking. But I am not sure it can fit nicely into current
frontend architecture.
