1 Introduction

This Wiki page describes an experiment targeting execution of Haskell programs on top of the Erlang Virtual Machine (BEAM). Haskell source code is compiled to Yhc Core with York Haskell Compiler (Yhc), then the program further discussed converts Yhc Core to Core Erlang; finally Erlang Compiler (erlc) compiles Core Erlang to the BEAM file format which can be loaded and executed by the Erlang VM.
