The Python programming language supports object-oriented programming using a simple and elegant model that treats member variables, methods, and various metadata as instances of a single kind of `attribute'. While this allows a simple implementation of an interpreter that supports advanced metaprogramming features, it ...

In this paper we present CASM, a general purpose programming language based on abstract state machines (ASMs). We describe the implementation of an interpreter and a compiler for the language. The demand for efficient execution forced us to modify the definition of ASM and we discuss the impact of those changes. A novel ...
