GNU epsilon
https://www.gnu.org/software/epsilon/
Strongly-typed omega-order programming language.
'GNU epsilon' is a purely-functional strongly-typed omega-order language, moving towards Lisp in that it allows dynamic management of source code at runtime. It is oriented to ease of development and readability. The static scoping rule and the type checkings at compile-time should make the language "safe".
Its features include:
- static scoping
- first-class functions
- Hindley-Milner type system with type inference
- modules
- synonym, concrete and abstract types, with polymorphism
- a scanner generator
- a purely functional I/O system, inspired by Haskell
- can generate C code, Scheme code, and bytecode for a virual machine
The package currently includes a compiler, interpreter, runtime system, and garbage collector. Planned or not yet finished: parser generator, classes, an extensive library, optimizer, partial evaluator, pretty-printer, an Emacs mode, parellel implementation for SMPs and clusters, interoperability with other languages via CORBA.
