The Alcool-90 Experiment - Experimental ML extension with run-time overloading and type-based notion of modules, functors and inheritance. Large HTML text document.
Dependent ML: DML - Conservative ML extension, has type system to enrich ML with restricted form of dependent types, to allow many interesting program properties: memory safety, termination can be captured in type system and thus be verified while compiling. Description, code samples, downloads.
Extended ML - EML is a framework for specification and formal development of Standard ML programs. Description, publications, tool support, education resources.
MetaML - Metaprogramming ML, needs SML first; part of OGI Mustang Project for Staged Programming. Pacific Software Research Center; download, install instructions, links.
MLRISC - Framework for customizable, retargetable and optimizing compiler back ends, written in Standard ML. Successfully retargeted to many architectures. Deals elegantly with special requirements imposed by execution model of different high-level, typed languages.
MLton - Whole program optimizing compiler for Standard ML.
Poly/ML - Standard ML full implementation: compiler and environment, has libraries for MS Windows, X Window. [Open Source]
Standard ML of New Jersey - SML/NJ is a compiler and programming environment for SML, with associated libraries, tools, documents. Descriptions, news, downloads (Unix, Windows), literature lists, FAQs, links, contacts. [Open Source, Lucent]
TILT - TIL-Two compiler; goal: make compiler for ML-family languages (SML'97, Caml Special Light, KML) that uses types throughout compiling to emit better code without losing safety or correctness; joint effort with Carnegie Mellon. Descriptions, papers, people, links. Cornell.
TILT Compiler - Self-checking Standard ML compiler, uses Typed Intermediate Languages; while compiling, types are translated with code, type-checking occurs to check compile results; funded by NSF. Descriptions, license, mail list, downloads, links. Carnegie Mellon.
