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.

EML is a framework for specification and formal development of Standard ML programs. Description, publications, tool support, education resources.

Whole program optimizing compiler for Standard ML.

SML to Java bytecode compiler, based on Persimmon's MLj.

Standard ML full implementation: compiler and environment, has libraries for MS Windows, X Window. [Open Source]

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]

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.
