[Haskell-cafe] Infix instance headers

[Bas van Dijk]

Simon,

I discovered that the following example also won't parse in ghc-6.12.1
because of the infix 'MayOpen' constraint:

with ∷ (Resource resource, MonadCatchIO pr)
     ⇒ resource
     → (∀ s. s `MayOpen` resource ⇒ RegionalHandle resource (RegionT s
pr) → RegionT s pr α)
     → pr α

Is this also fixed by your previous patch?

regards,

Bas
