@kr1sp1n @neauoire The C implementation should be able to be invoked by running..

./bin/modal lisp.modal

.. from the top level directory after running `make`.

The old `define` syntax is replaced with `<>` in the C implementation. You can add..

`define <> define`

.. to the top of any Modal source file to run it with the Python implementation. Bear in mind, I/O won't work in the Python implementation.
