Hello glasgow-haskell-users, should the following work in 6.6? -- | Alloc the mutable byte vector having `elems` elements of required type allocUnboxed :: (STorIO m s, Integral elems, Unboxed a) => elems -> m (MUVec s a) allocUnboxed elems :: m (MUVec s a) = -- it's line 149 allocUnboxedBytes (fromIntegral elems * sizeOfUnboxed (undefined::a)) the problem is that it works in 6.6rc1, but user reports that his compiler (i think, 6.6 release) can't compile it saying: Data/Unboxed.hs:149:0: Parse error in pattern may be it's because september's changes in scoped tyvars handling? how i can convert this code retaining compatibility with Hugs? -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
