data-lens-light

This is a minimalistic lens library, based on data-lens.

The main differences from data-lens are:

  • reduced API
  • minimal set of dependencies
  • data-lens, data-lens-fd and data-lens-template exported through a single module in a single package
  • MonadState combinators return ()
  • strict MonadState combinators force the whole state, too

(The above list may be not exhaustive. Compatibility with data-lens is not a goal.)
