Senpai, were you looking for this bento box?

Dale is a system (no GC) programming language that uses S-expressions for syntax and supports syntactic macros. The basic language is similar to C, with the following additional features:

local type deduction;
overloaded functions;
anonymous functions;
function structs;
reference parameters;
initialisers and destructors;
namespaces;
modules;
concepts; and
compiler introspection.

Nice. Is it PRODUCTION QUALITY yet?
