What about recommending against “clever macros” that use ‘syntax-local-binding’, or documenting the limitation in how ‘local-eval’ and ‘syntax-local-binding’ would interact? After all, the point of ‘local-eval’ is to provide a compatibility later with 1.8, and ‘syntax-local-binding’ didn’t exist there. Thanks, Ludo’.
