I personally would welcome a renewed effort to update Standard ML. Successor ML 
is clearly dead (better than Standard ML, which is ironic given its rather 
arrogant manifesto), but a small group of well-organised people might be able 
to put together some modest and well-thought-out revisions to the language. But 
I don't think that making ad hoc changes to Poly/ML would be a great idea.
