Programming language Theme-D

I have implemented programming language Theme-D, which is a Scheme-like programming language with static typing. Some properties of Theme-D include:
- Static type system
- A simple object system
- Multi-methods dispatched runtime (and also compile-time)
- Parametrized (type parameters) classes, types, and procedures
- Signature types resembling Java interfaces but multiply dispatched
- A module system
- Two kinds of variables: constants and mutable variables

I have also ported (a subset of) guile-gnome GUI library to Theme-D. Its homepage is located at

A Framework for Gradual Memory Management

I do not know how much interest this community has in the intersection of programming languages, memory management and type systems, but for those intrigued by such topics, you might find this paper on Gradual Memory Management to be worth reading.

It proposes that a language's compiler offer more sophisticated type systems that enable a program to flexibly support multiple memory management mechanisms for improved performance, and do so with safety guaranteed at compile time. The described type systems build up from Rust's lifetime-driven owner/borrower model as well as Pony's reference capabilities (mutability/aliasing permissions). The paper also references Microsoft's experimental work on Midori.

I welcome any feedback or questions.
