Sanguinius [Discontinued]

sanguinius is an experimental half-finished basic scheme interpreter written in swift. In order to build sanguinius from sources, the following are required:

• swift 2.2-dev

If all requirements are met, perform the following steps:

    swift build

You can run sanguinius by typing:

.build/debug/sanguinius

inside the project directory.

** The implementation is completely broken and very slow **
