I know of none. On the other hand, block-scoped variables are implemented in: * C * C++ * Java * Rust * Lua * JavaScript (not by default, as opt-in) * Scheme * Common Lisp (as opt-in) * ML * Ocaml * Haskell * very long list of other languages... The aim of the block scoping proposal is to make Python *not worse* than these other languages, instead of adding funny workarounds again.
