Here's the error message:
[info] == console ==

log.error(Message(countElementsAsString(ERROR.count, "error") + " found"))

two errors found

There are lots of implicit objects/conversions within sbt which handle
compatibility issues within the compiler. I think this is fine for now
and we can do the same for the above error.

Ah. Been pretty focused on the binary compatibility of the library jar;
we make no such guarantees for compiler. Obviously that's not good
enough -- at the last, "compiler-interface" needs to retain binary
compatibility. This provides further motivation to establish better
boundaries in the compiler jar. I think this will take a bit of time.
(Fixing the error shown above is easy, but the question of what needs to
retain compatibility and the verification that it is indeed compatible
is more uncertain.)
