@hackage secdh0.2

SECDH stands for "Stack-Environment-Code-Dump-Heap", and is an abstract machine based on Landin's classic SECD machine for evaluation of lambda-calculus expressions. This machine adds a heap of suspension cells to the structure managed by the machine, allowing fully-lazy evaluation, similar to Haskell. The machine operates directly on the syntax tree, as Landin's machine does. The entire implementation, including parser, evaluator, and garbage collector, occupies just over 1100 lines of code.
