Module documentation for 0.9.4

Just as there's a Foldable class, there should also be an Unfoldable class.

This package provides one. Example unfolds are:

  • Random values

  • Enumeration of all values (depth-first or breadth-first)

  • Convert from a list

Some examples can be found in the examples directory.
