Features:

Small and simple implementation
Statically typed with type inference
Structural typing with extensible records and variants
Lazy evaluation
Convenient use from Haskell
Whitespace insensitive syntax
Type annotations for supporting first-class modules and schema validation
Built-in support for various data types like ints, doubles, bools, chars, and lists
Support for fixed-points without recursive records

Summary:

Expresso is a minimal functional programming language with a focus on embedding and extensibility. With features like extensible records, lazy evaluation, and compatibility with Haskell, it offers a simple yet powerful tool for various use cases such as configuration management and data exchange. The language employs a clear syntax and type system, making it ideal for developers looking for a lightweight yet expressive language for their projects.
