Austin Ziegler and I were talking a while ago about how it'd be cool
to have an option like:

  ruby --warn1.9

As far as I know, such initiatives haven't taken place yet, but they'd
be quite welcome.  I want to start working on 1.9 compatibility for
some of my projects in the next couple months, to be an 'early
adopter'.
