That is precisely what take 1 OSR is for.

At the risk of repeating myself, if Pervasives defines a plain variant  
('a, 'b) may_fail = Success of 'a | Error of 'b, I don't care about  
polymorphic variants. The thing is that for now I don't want to depend  
on hypothetical improvements to the standard library performed outside  
the scope of the base distribution. Take 1 allows this, take 2 doesn't  
allow it.
