Thanks for the explanation.  Maybe some Wiki page with a list of syntax and fixity proposals, explanations, comments, and votes could be made for this?

One more idea: how about '>-' for 'flip ($)' and '-<' for '$', by analogy with '>>=' and '=<<'?

    y = 3 >- \x -> x * x                -- y == 9
