Hey! Welcome to the Basil repository. :)
Basil is currently a work in progress. The implementation present here isn't anywhere near usable, and the language isn't really set in stone. But if you'd like to play around with it, or see a more in-depth description of the language as it currently stands, please feel free to clone the project or take a look at the specification draft.
As of August 2020, the Basil Programming Language has been reworked, and is now housed at https://github.com/basilTeam/basil.
