T13784.hs:29:28: error: [GHC-25897]
• Couldn't match type ‘as’ with ‘a : Divide a as’
Expected: Product (Divide a (a : as))
Actual: Product as1
‘as’ is a rigid type variable bound by
the instance declaration
at T13784.hs:25:10-30
• In the expression: as
In the expression: (a, as)
In an equation for ‘divide’: divide (a :* as) = (a, as)
• Relevant bindings include
divide :: Product (a : as) -> (a, Product (Divide a (a : as)))
