at least we need to support GHC 8.2, 8.4, 8.6, 8.8.

For signaling finalization from Haskell GC, ForeignPtr is necessary. Originally, fficxx used ForeignPtr but for simplicity, we dropped the support. It's good to have optional support for Ptr/ForeignPtr.

By default, fficxx generate FFI code as safe FFI. However, for performance, it is desirable to allow users to specify `unsafe` for a certain methods. Make this opt-in.

funcitons with default parameters like `int foo( char a, int b=0, bool=true )` had better be handled automatically. Currently, it is just manually handled with alias. Suggestion is `foo_`, `foo__`...

fficxx types are full of partial records. We should get rid of them.

Migrate from haskell-src-exts to ghc-source-gen

It's time to move towards modern GHC API.

for better coding

Currently, binding library developer should embed C++ interface as a Haskell data and write a Haskell script to generate code. The data structure for C++ interface is pretty simple, so...

Plain Old Data C struct support

POD C struct had better be treated as Storable for a better interoperability with Haskel (like c2hs)

OverlappingInstances is deprecated.
