}

one of the best use cases for semantic coloring would be realizing that these are two different things named var1.

Currently semanticolor doesn't actually know about the semantics (I know, I know) of your program. If it could take advantage of tree-sitter grammars (I have an issue open for what we need in order to support them: https://github.com/atom/atom/issues/19151), we might be able to do something like this...
