Parse failure ("Illegal class assertion") on parenthesised single-item class contexts

[ganesh]

This is in 0.5.3 (shouldn't that be listed in the versions field?)

module Test where

foo :: (Eq a) => a -> a
foo x = x

ParseFailed (SrcLoc {srcFilename = "test.hs", srcLine = 3, srcColumn = 15}) "Illegal class assertion"

If I remove the () around Eq a, the problem goes away.

It should be listed yes, I've updated the trac settings and set this to the proper version.

This should be an easy fix.

It certainly wasn't hard to fix, just a mental lapse when writing the code for checking assertions. Case closed.
