Fixes #2353, supersedes #2354.
Returning a
nilpointer to a struct implementing the interface is bad form, and a bug (thenildoesn't actually implement the interface: it panics).I don't love naked returns in this big a function either, but the rest of the assumptions in #2354 were problematic, and were blocking the fix.
