1 Sometimes using Test::More's is test isn't good enough. Its diagnostics may make
2 it easy to miss differences between strings. By using is_binary instead of is,
3 the "!" tells us that the lines differ, and we can quickly scan the bytes that
4 make up the line to see which differ. When comparing very long strings, we can
5 stop after we've seen a few differences.
