Yes, this would be very interesting indeed. A list of the rules which

dmd uses internally for inlining functions and methods would be really nice.

Well if I read the code correctly the following is not supported:
- nested inline?
- variadic functions (T t, ...)
- synchronized
- imported functions
- functions with closure vars
- virtual functions that aren't final
- functions with out, ref or static array parameters
- functions with more than 250 elementary expressions


Created my own little inline dumping patch:
