Build Status

This package explores strict mutable data structures in Haskell.

In particular, pointer-based data structures are effectively 'half price' due to the encoding used.

However, the result is that if you use the slot and field system wrong, you can and will SEGFAULT.

This means the Internal modules are very much internal.

Some documentation is available at
