No language can serve all of the people all of the time, but I think
we should just do our best with a single standard.  I think that the
complexity of multiple languages / layers / standards would not be
worth the payoff.

Have you looked at the Helium language / compiler?  It's a
stripped-down version of Haskell for teaching.  Maybe that's what
you're actually suggesting?  I think this is a great idea :)
