type Lens' σ α = Lens σ σ α α Source
This is the same type as the type from the lens library with the same name.
In case it is already import from the lens package this should be hidden from the import.
type Lens σ τ α β = forall φ. Functor φ => (α -> φ β) -> σ -> φ τ Source
This is the same type as the type from the lens library with the same name.
In case it is already import from the lens package this should be hidden from the import.
type Iso σ τ α β = forall π φ. (Profunctor π, Functor φ) => π α (φ β) -> π σ (φ τ) Source
