Long story short

I would like to use a pattern like:

try:
    do_something()
except SomeException as e:
    raise HTTPInternalServerError(reason='My message') from e

with cause information retained. Does it make sense to implement HTTPException.__bool__() to always True?

Expected behaviour

Two tracebacks separated by The above exception was the direct cause of the following exception:

Actual behaviour

The cause information is lost, because traceback.TracebackException evaluates the truthiness of the exception value to determine whether cause lines are produced. For HTTPException, truthiness is resolved via StreamResponse.__len__() which returns 0.

Steps to reproduce

Your environment

Yes, looks like __bool__ is the best we can do in the situation.
