I need to resolve a name clash between two different Haskell modules
that want to use the same infix operator (<*>).  The Haskell 98
report says that

    modid.varsym

is permitted, but I can't get it to work. In their entirety here are Test.hs:

    module Test
    where

    import qualified Test2 as T

    three = T.<*>

and Test2.hs:

    module Test2
    where
    (<*>) = 3

But trying to compile results in an error message:

    Test.hs:6:12: parse error on input `T.<*>'

I tried T.(<*>) but that doesn't work either (as indeed the Haskell 98
report says it should not).

How can I refer to a symbolic name defined in a module imported by
`import qualified`?

This works:

   three = (T.<*>)
