[Hat] Tracing of standard libraries

[O.Chitil at kent.ac.uk]

Hi Matthias,

Hat supports Haskell 98 plus a few additional libraries, but Unsafe is not
one of these libraries. A Google summer of code project is still under way
to improve this situation, but that will still take time.

The quick fix is to copy a library to your own directory and transform it
together with your program. However, direct transformation only works on
libraries written in Haskell 98 itself and Unsafe will hardly be of that
kind. There are ways for wrapping code not written in Haskell 98, but that
requires more handwork (you can see how the core parts of the Haskell 98
libraries are dealt with).

Btw, both Malcolm and I are currently in Freiburg so we could easily meet.

Ciao,
Olaf
