families, which are similar to Haskell's GADTs, but they can be indexed by
values and not just types. It also has parameterised modules, mixfix operators,
Unicode characters, and an interactive Emacs interface (the type checker can

Agda is also a proof assistant: It is an interactive system for writing and

Martin-Lof. It has many similarities with other proof assistants based on
