I was just thinking about providing the removed lines and the added lines at
the same time into the method (just like what a patch file looks like). The
exception here can probably be enhanced to compare the content of `removed`
with `from`. Two blocks of code (call and callback) would be needed if a
consumer or predicate is used, and I don't feel it's worth doing. Here I've
already trimmed the lines to make sure whitespaces do not matter.
