Fwiw, we already had that situation. The following code {-# LANGUAGE UnicodeSyntax #-} module Foo where x₀ ∷ Double x₀ = 1.5 compiles with GHC ≥ 7.2, but with GHC 7.0 fails with: GHCi, version 7.0.4: http://www.haskell.org/ghc/ :? for help [1 of 1] Compiling Foo ( foo.hs, interpreted ) foo.hs:5:2: lexical error at character '\8320' Failed, modules loaded: none.
