Oh, I know. That evil eval in there is an open door for all sorts of fun
stuff to happen.  

One more reason why (I think) there should be a newbie-friendly way of
getting my canonical

print '%(self.hello)s' % locals()

to work.  Having the cleanest (IMO) solution involve both stack frame
manipulations and an eval() is not my idea of newbie-friendly ;)
