1. productMaybeWith :: (a -> b -> Maybe c) -> [[a]] -> [[b]] -> [[c]]

   extrapolate	Test.Extrapolate

   Take the product of lists of tiers by a function returning a Maybe value discarding Nothing values.

2. products :: [[[a]]] -> [[[a]]]

   extrapolate	Test.Extrapolate

   Takes the product of N lists of tiers, producing lists of length N. Alternatively, takes as argument a list of lists of tiers of elements; returns lists combining elements of each list of tiers.

   products [xss]  =  mapT (:[]) xss
   products [xss,yss]  =  mapT (\(x,y) -> [x,y]) (xss >< yss)
   products [xss,yss,zss]  =  product3With (\x y z -> [x,y,z]) xss yss zss
   

3. product3With :: (a -> b -> c -> d) -> [[a]] -> [[b]] -> [[c]] -> [[d]]

   extrapolate	Test.Extrapolate.Core

   Like productWith, but over 3 lists of tiers.

4. productMaybeWith :: (a -> b -> Maybe c) -> [[a]] -> [[b]] -> [[c]]

   extrapolate	Test.Extrapolate.Core

   Take the product of lists of tiers by a function returning a Maybe value discarding Nothing values.

5. products :: [[[a]]] -> [[[a]]]

   extrapolate	Test.Extrapolate.Core

   Takes the product of N lists of tiers, producing lists of length N. Alternatively, takes as argument a list of lists of tiers of elements; returns lists combining elements of each list of tiers.

   products [xss]  =  mapT (:[]) xss
   products [xss,yss]  =  mapT (\(x,y) -> [x,y]) (xss >< yss)
   products [xss,yss,zss]  =  product3With (\x y z -> [x,y,z]) xss yss zss
   

6. product2Strategy :: (a -> b -> r) -> (r -> (a, b)) -> MergingStrategy a -> MergingStrategy b -> MergingStrategy r

   grisette	Grisette.Core

   Useful utility function for building merge strategies for product types manually. For example, to build the merge strategy for the following product type, one could write

   data X = X { x1 :: Int, x2 :: Bool }
   product2Strategy X (\(X a b) -> (a, b)) rootStrategy rootStrategy
   :: MergingStrategy X
   

7. product2Strategy :: (a -> b -> r) -> (r -> (a, b)) -> MergingStrategy a -> MergingStrategy b -> MergingStrategy r

   grisette	Grisette.Internal.Core.Data.Class.Mergeable

   Useful utility function for building merge strategies for product types manually. For example, to build the merge strategy for the following product type, one could write

   data X = X { x1 :: Int, x2 :: Bool }
   product2Strategy X (\(X a b) -> (a, b)) rootStrategy rootStrategy
   :: MergingStrategy X
   

8. productG :: Graph -> Graph -> Graph

   hgal	Data.Graph.Construction

   No documentation available.

9. production :: Bool

   hledger-web	Hledger.Web.Import

   No documentation available.

10. product' :: RealFloat a => [Log a] -> Log a

    mcmc	Mcmc.Prior

    Intelligent product that stops when encountering a zero. Use with care because the elements are checked for positiveness, and this can take some time if the list is long and does not contain any zeroes.
