When I say "exotic" I mean to Pythonistas and Lispers alike.

Hissp has a bunch of special literals and object types for generating and passing around Python imports, running Python at read time, etc. So it looks different from both Python and Lisp.

It has its own Lisp reader Lissp, but also offers a syntax that allows you to express Hissp with Python tuples (so, within native Python code), called readerless mode. The Lissp syntax also has constructs for inlining literal Python.

Quite interestingly a sister package Hebigo offers a reader an indentation-sensitive syntax, bringing the whole thing full circle. It's not similar to Wisp or Sweet Expressions, but rather something that looks more Python-shaped.
