the MPTC Dilemma (please solve)

[Ravi Nanavati]

My personal opinion is that while a delay might resolve this particular 
dilemma, I don't see a delay as preventing *future* dilemmas along the 
same lines. As long as Haskell implementations actively experiment with 
the language (and I don't think this is something we'd want to 
discourage) I'd expect that there would always be features that people 
find highly useful that aren't straightforward to standardize for one 
reason or another. And given the volume of extensions most "real-world" 
Haskell programs are using today, I think there's plenty worth 
standardizing regardless of how things are resolved with this particular 
dilemma.

P.S. I suppose this is also an argument for some sort of 
"extension-blessing" mechanism. If we're expecting a future in which a 
thousand more extensions will bloom, it seems like a good idea to create 
some mechanism for implementers and users to manage that complexity.
