`sys.excepthook` is a single function (not a list of them).
This means: at any moment a single `excepthook` is effective.
If you need a modular design, use a dispatcher function
as your `excepthook` associated with a registry (e.g. a `list`).
The dispatcher can then call all registered function.

Thank you both. I'll give this a try. I think it would be nice if the
standard library function atexit.register would be improved, such that the
registered functions would not only be called upon (a) normal program
termination, but that one could also register functions that are called
(b) upon error (c) unconditionally. Much like (a) try - (b) except - (c)
finally.
