"""
Welcome to Counterexamples in Type Systems, a compendium of horrible
programs that crash, segfault or otherwise explode.
The "counterexamples" here are programs that go wrong in ways that
should be impossible: corrupt memory in Rust, produce a
ClassCastException in cast-free Java, segfault in Haskell, and so on.
This book is a collection of such counterexamples, each with some
explanation of what went wrong and references to the languages or
systems in which the problem occurred.
It's intended as a resource for researchers, designers and
implementors of static type systems, as well as programmers interested
in how type systems fit together (or don't).
