A dynamic typed scripting language for embedded use in applications.
## Warning: Project is under development and not useable now.
## Features
- [ ] **Gradual Typing**: Support for optional type hint.
- [x] **Security**: Diatom is completely isolated and is only able to interact with its host.
- [x] **ADT**: Diatom use algebraic data type.
- [x] **No Null, No Exceptions**: Diatom encourages the use of `Maybe` **functor** and **monad**. The concept of `null` and `exception` in other languages like Java is completely useless in Diatom.
- [x] **Impure Functional**: Diatom makes everything mutable and public like Python. We also support a little OOP in `data`(aka `class` in OOP languages) declaration.
- [ ] **Native Speed**: Given every variable is marked, diatom is able to theoretically reach C/C++ level speed.
