I had a closer look at the source code and it looked fine. I did realise though
that I should at the changes you made, rather than just the resulting code :).
So that will a second round.
As for the use of tcl_interp: this is required because the transformation
routine does not take an extra argument that would allow us to store the
original interpreter in. So the code stores a pointer to the interpreter for
later use. This is somewhat unfortunate, as it introduces problems for a
multithreaded application, but I see no possibility to do otherwise.

Arjen
