Oh wait, this works for me! It was the specific thing I was trying to
do (wrapping an NSError instance in an AnyError) that breaks which
was leading me to think importing the Result library into the REPL
wasn't working:
$ swift -I.build/debug -L.build/debug -lResult
Welcome to Swift version 3.0.2 (swift-3.0.2-RELEASE). Type :help for
assistance.

Execution interrupted. Enter code to recover and continue.
Enter LLDB commands to investigate (type :help for assistance.)

So it looks like I have a Foundation on Linux bug? I will do what the
REPL suggests and see if I can figure out what's going on.
Thanks, Robert.
