If you type %pdb *before* running your scripts, then any exception
that fires will automatically activate pdb.

But for a while we've had a more convenient way to access pdb, which
is the new %debug command.  At any time if you simply type %debug, the
pdb debugger will activate into the last unhandled exception.  So as
long as you don't wait too long after seeing an exception (since the
system only works with the *last* one, if you get a new exception from
a typo at the command line you lose the chance to inspect your
program), you can use it in a more fluid way than letting %pdb
forcefully activate every single time.
