Please do not hack the already-overcomplicated query in getFuncs without
bothering to adjust the long comment that describes what it's doing.
I have a vague feeling that the code for dumping casts and/or transforms
may have some assumptions that the underlying function is also being
dumped. Although maybe the assumption was really only what's fixed here,
ie that there be a DumpableObject for the function. Anyway, take a close
look for that.
Looks reasonable otherwise.
