Re-using it between compiler invocations is more tricky because it is only legal if generator function and all stuff they indirectly use have not changed too. Ignoring this requirement can result in nasty build issues that are only fixed by clean build. Too harmful in my opinion.


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.
