Yhc
The York Haskell Compiler is an open source bytecode compiler for the functional programming language Haskell; it primarily targets the Haskell '98 standard. It is one of the four main Haskell compilers.
Yhc is based on the nhc98 Haskell compiler, and is intended eventually to be a more portable, cleaner, better performing rewrite of nhc98 with more and better features. In particular, Yhc features integrated support for , the Haskell tracer. The Yhc project uses Darcs for version control. It was originally developed at the Department of Computer Science at the University of York in the UK.
