**Lamb** is a toy dynamically typed functional programming language It's not meant for real-world use but for educational purposes on writing an interpreter with pattern matching in Haskell. **Features** * No re-assignment (i.e., once you bind a value, you can't re-assign it) * Pattern matching: `f([]) -> "nothing". f([a]) -> one thing".` * Imperative I/O * Higher-order functions * Partial evaluation on curried functions **Hello World!** `examples/helloworld.lamb`: hello() -> "hello, " + hello("world"). hello(object) -> object + "!". putstrln(hello()). **License** Licensed under the terms of the zlib license.
