I've finally released another version of Wrapl. This one is written in XDS Modula-2/Oberon-2 and compiles directly to machine code in memory which is then executed. There is not much of a library yet, nor is there much documentation, however, the interpreter works and is capable or interpreting complex expressions. Since the compiler generates Pentium machine code, at least a Pentium processor is required, however the source code compiles on both Linux and Windows, and binaries for both platforms are included.
The downloads are available from http://wrapl.sf.net.
