T15648.hs:23:21: error:
• Couldn't match type: (a0 GHC.Prim.~# b0) -> JankyEquality a0 b0
with: JankyEquality a a
Expected: JankyEquality a b
Actual: (a0 GHC.Prim.~# b0) -> JankyEquality a0 b0
• Probable cause: ‘Jank’ is applied to too few arguments
In the expression: Jank
In an equation for ‘legitToJank’: legitToJank Legit = Jank
• Relevant bindings include
legitToJank :: LegitEquality a b -> JankyEquality a b

T15648.hs:30:10: error:
• Couldn't match expected type: (a GHC.Prim.~# b)
-> b GHC.Prim.~# a
with actual type: b GHC.Prim.~# a
• In the expression: unJank $ legitToJank $ mkLegit @b @a
In an equation for ‘ueqSym’:
ueqSym = unJank $ legitToJank $ mkLegit @b @a
• Relevant bindings include
