I must say though, that I don't like the reasoning that we can put in fractional fixities because it's a small change. The way to hell is through a series of small steps. If using integers to express fixities is a bit of a hack, switching to rational numbers is a hack on top of a hack.

Well, It's a _conceptually_ simple idea, one that doesn't make understanding the language much harder.

Also, it provides an infinite space for fixities. I think the problem 'binds tighter than X but not as tight as Y', where X and Y are only fixity integer apart is somewhat common, and this would fix it.

In school we learnt "dot operations (multiplication, division) bind more tightly than dash operations (addition, subtraction)". I imagine we would have learnt "dot operations have precedence 7, dash operations have precedence 6". :-)
