ML Module Mania: A Type-Safe, Separately Compiled, Extensible Interpreter (Abstract)

To illustrate the utility of a powerful modules language, this paper presents the embedded interpreter Lua-ML. The interpreter combines extensibility and separate compilation without compromising type safety. Its types are extended by applying a sum constructor to built-in types and to extensions, then tying a recursive knot using a two-level type; the sum constructor is written using an ML functor. The initial basis is extended by composing initialization functions from individual extensions, also using ML functors.
