You're correct, I missed that.  Exception is derived from Throwable in
druntime, and Throwable has a field 'info' of type TraceInfo with
opApply in its interface.

But it doesn't work, at least with DMD 2.023 on Windows.  Attempts to
access this field cause object.Error: Access Violation.  I didn't try to
investigate further though.
