Comment 2 for bug 675323

Stack levels are being dealt with in bug 788974.

Matchee often printed twice (once by assertThat, once by matcher as part of mismatch) is bug 593190.

Remaining issues on this ticket:
 * Matcher argument printed twice, once by assertThat as part of str(matcher), once by matcher as part of mismatch
 * "Paste test output into a repl" → not sure what this actually means or how we're failing
 * assertThat version "uses longer more complicated words" → I can kind of see this, but would like more clarity. Is this an issue with assertThat, with Equals, with both?
