sapling
sapling is a "micro-language" that I'm working on to investigate Tree Calculus .
It offers a minimal amount of syntax sugar:
toperator behaving by the rules of Tree Calculus- Variable definitions
- Lambda abstractions
- List, Integer, and String literals
This is an active experimentation project by someone who has no idea what they're doing.

Tree Calculus was discovered by Barry Jay.
treecalcul.us is an excellent website with an intuitive playground created by Johannes Bader that introduced me to Tree Calculus. If sapling sounds interesting but you don't want to figure out how to compile Haskell, check his site out.
