I agree. I don't declare operators very often, and when I do I always struggle to remember which way round the precedence numbers go. [...] (Anything else we can bikeshed about while we're at it?)

Perhaps "before" and "after" clearer than "higher" and "lower"?

I would pick "tighter than" and "looser than", but I suppose that "before" and "after" are also clear enough. Or maybe "inside" and "outside"? I don't think that we really need a new keyword for precedence declarations. The current "infix" would suffice if the default was for operators to be non-fix and of indeterminate precedence. Multiple fixity declarations for the same operator should then be allowed. Or perhaps just require that separate declarations use the same "infix[lr]?" keyword. Twan
