Ok, i've watched issue and pull.

I have some questions:

1. Do we really need support of old golang version?
2. I'd prefer to provide new MigrationSource implementation, instead of changing behaviour of previous existed. Is it ok for you?

Is there a reason why we need to break compatibility with older Go versions?

No, there is no suitable reasons. I've just ask your opinion.

Would you prefer: to make me commits, comments to previous pull or send newest?

Then let's not do that. We never break compatibility if we can avoid it.

Let's work together on the other PR.
