IIFE exist, but are cumbersome to type/read in most languages. C++ is probably the winner by syntax and semantics here. false positive rate would be way too high The key idea is not to have identical blocks, but to have a way to overview changes in similar code, similar by origin and design. It’s a snippet diff tool, not a typo autocorrector. There’s no false positives cause if “common foo” has zero diff in all cases, it probably should be “foo(…)”.
