Re: [Haskell-cafe] Generic "to tuple" function

I have tons of code like this:

from_tuple = uncurry MLBBoxScoreGameBreakdownXml to_tuple (MLBBoxScoreGameBreakdownXml a h) = (a,h)

The first function, from_tuple, generalizes easily with `uncurryN` from Data.Tuple.Curry. But I'm wondering, is there any generic function that will take a simple data type and cram it into a tuple?

So instead of writing,

from_tuple = uncurryN MLBBoxScoreGameBreakdownTeamXml to_tuple (MLBBoxScoreGameBreakdownTeamXml w x y z) = (w,x,y,z)

I could just do,

from_tuple = uncurryN MLBBoxScoreGameBreakdownTeamXml to_tuple = toTupleGeneric

because things get real ugly when there are ~20 fields in the data type.

Should be easy to do with the generics-sop package. Roman
