Show HN: lazy, functional data structures; stack-safe recursive lambdas for Java (github.com)

procrastination is a modular, zero-dependency library for Java 11 that provides:

* lazily evaluated, memoizing, purely functional data structures

* ad hoc pattern matching

* an extensible, reusable alternative to Java 8's Stream

* stack-safe tail-recursive lambda expressions via trampolines and fixed points

If you have JDK11 and a recent version of Maven installed, you can easily play around with this in jshell by cloning the repository, and from the root directory, running mvn compile and jshell procrastination.jsh.

I would be very grateful for any feedback.
