Or you could use grn for LSP rename[1] in Neovim and it will rename all references across the project. VSCode and other IDEs have a similar feature, but compared to multi-cursor that's cheating.

I'll give you that using the AST to select the references is an interesting addition to multi-cursor, but I still don't see how they would be useful compared to my current workflow.
