Can you show us a simple(!) example, I'm not sure I quite understand
the parameters of the problem.
How does the XSI GUI execute the code you pass to it?
If it executes it by itself then it why not just write the callbacks
## create a foo wrapper
real code here
Or do you need to call them too?
This might be a valid use for exec:
foostr = '''

But I'm not sure what the restrictions of 'on the fly' are. How
close to runtime must the definition be? Could it be
parameterised by a format string?
