It's not at all obvious to the casual reader why `All` is defined as it is, and in particular what `SListI` is really about. This should be explained.
Packages that define orphan instances don't always need all their dependencies to be built. For example, suppose package `compat` depends on package `plain` and just defines instances that appear in...
The explanation is pretty sparse, and there aren't any instances to get a sense of what this class is for. I have no idea what it means.
```haskell newtype DefaultJSON a = DefaultJSON a instance (Generic a, GToJSON Zero (Rep a), GToEncoding Zero (Rep a)) => ToJSON (DefaultJSON a) where toJSON (DefaultJSON a) = genericToJSON defaultOptions a...
`parseWith` runs a parser and returns a `Result`. This `Result` will _always_ be either `Done` or `Fail`, but the type leaves open the possibility of `Partial`. This means that library...
Use `copyAddrToByteArray#` to append (strict) `ByteString`s. In the (admittedly relatively unusual) case where GHC can see that one or both of the arguments have known small length, it may implement...
Allow GHC to unbox the results of the general `ByteString` creation functions when it's so inclined.
`append` unconditionally uses FFI calls to `memcpy` for both bytestrings. If one or both of them are known at compile time to be very short, this is inefficient. I believe...
`append` and `times` should be able to get away with `unsafeWithForeignPtr`, but they use `unsafeCreate`, which uses `withForeignPtr`.
Going through strict bytestrings is totally unnecessary and wasteful. Here's one direction. I don't know if it's as efficient as possible, but it's surely more efficient than performing an unnecessary...
