[swift-users] Importing Foundation or Glibc in REPL on Ubuntu 16.10 failing

[Michael Gottesman]

Interesting... it looks like we /do/ have an integration test that imports glibc into the repl:

https://github.com/apple/swift-integration-tests/blob/master/repl/test-repl-glibc.py <https://github.com/apple/swift-integration-tests/blob/master/repl/test-repl-glibc.py>

Probably could use one that imports Foundation though.
