Template.hs:7:1: warning: [-Wsemigroup (in -Wcompat)]
Local definition of ‘<>’ clashes with a future Prelude name.
This will become an error in a future release.
Template.hs:13:3: warning: [-Wnoncanonical-monoid-instances (in -Wcompat)]
Noncanonical ‘(<>) = mappend’ definition detected
in the instance declaration for ‘Semigroup S’.
Move definition from ‘mappend’ to ‘(<>)’
Template.hs:16:3: warning: [-Wnoncanonical-monoid-instances (in -Wcompat)]
Noncanonical ‘mappend’ definition detected
in the instance declaration for ‘Monoid S’.
Define as ‘mappend = (<>)’
Template.hs:20:15: warning: [-Wstar-is-type (in -Wcompat)]
Using ‘*’ (or its Unicode variant) to mean ‘Data.Kind.Type’
relies on the StarIsType extension, which will become
deprecated in the future.
Suggested fix: use ‘Type’ from ‘Data.Kind’ instead.
