Future home of fns proposed for core inclusion. Currently:

  • A set of short-circuiting "nil-safe" threading macros (e.g. -?>, -?>> and .?.)
  • An implementation of dissoc-in
  • An implementation of seqable?
  • A string interpolation macro (<<), originally described here.

For more details, please see the project's generated API documentation.
