This is something like:

(test.log) (a) file
dup (hello world!\n) writestring
closefile

The problem is that the files are parsed into memory and then executed 
later. You could perhaps modify the bind operator to wrap everything in 
some code that logs the procedure name before executing it, and then 
work backward from there.

For more accurate statistics, you'd have to augment the parser and 
stacks to keep track of line number information. That's what I meant
about not keeping much debugging information. It's not a small job,
but not impossible either.

Maybe Ray has some ideas.
