+1 for having the base __init__ API be the exception triple and then a TracebackException.from_exception() class method as an alternate constructor.

However, the redundancy between TracebackException.__init__() and TracebackException.from_exc_tuple() feels very strange to me. It leaves the __init__ working-but-undocumented and isn't a pattern I can recall seeing anywhere else in the standard library.

Would it be possible to just add the from_exception() class method and leave the documented (and only) API for building from a triple being the normal constructor call?
