[1 of 3] Compiling Algebra ( Algebra.hs, dist/build/Algebra.o )
Algebra.hs:121:21: error:
• Could not deduce (Semigroup b) arising from a use of ‘<>’
from the context: Group b
bound by the type signature for:
commuteWith :: forall b a. Group b => (a -> a -> b) -> a -> a -> b
at Algebra.hs:120:1-54
Possible fix:
add (Semigroup b) to the context of
the type signature for:
commuteWith :: forall b a. Group b => (a -> a -> b) -> a -> a -> b
• In the expression: f x y <> invert (f y x)
In an equation for ‘commuteWith’:
commuteWith f x y = f x y <> invert (f y x)
|
121 | commuteWith f x y = f x y <> invert (f y x)
