[Haskell-cafe] Fixity of ($) and (.) vs. (&) and (>>>)

With function composition I can easily write something like

    h . g . f $ expr

However if I want to write the equivalent in left-to-right composition

    expr & f >>> g >>> h

This is not possible due to a parsing error arising from the fixity of the
operators. (>>>) is provided by Control.Arrow and (&) by Data.Function. My
question is, would it not be better to *decrement* the fixity of (&) by one
or *increment* the fixity of (>>>) by one (probably rather the latter)?
