How to use with byebug?

[smtlaissezfaire]

Trying to investigate why something isn't working with a debugger like byebug is nearly impossible.

FakeFS overrides all of the file readers so byebug can't show source information.

doubt that's easy
... maybe by setting Byebug::File etc things, but that's hacky

What errors do you see in byebug?

See how I fixed pry #485, maybe that'd help you.
