[PATCH] MergeFunc: Avoid invalid merge of functions using different range metadata

[Stepan Dyatkovskiy]

Yes. Exactly ) For now, I propose to come back to initial patch; make sure tests has been fixed as I asked you in inline comments and, I think we apply it (Nick didn't object about it yesterday).
Then, after we replace ComparableFunction with new structure, you could introduce 'range' metadata merging.
Thanks for working on it!
