Re: [Haskell-cafe] Pointfree composition for higher arity

I find myself often writing this pattern:

someFun x y z = ...

fun y z = runFun $ someFun someDefault y z

or, alternatively:

fun y = runFun . someFun someDefault y

I very often write this too (wanting function composition, but with a two-argument function on the right hand side). The trick I picked up from somewhere is to do: fun = (runFun .) . someFun someDefault I'm not too keen on that, as it seems clumsy. I often end up writing the operator that you describe, but have never settled on a consistent name (since the obvious one to me, (..), is taken). Thanks, Neil.
