T8603.hs:13:10: error:
• No instance for (Applicative RV)
arising from the superclasses of an instance declaration
• In the instance declaration for ‘Monad RV’
T8603.hs:29:17: error:
• Couldn't match type ‘RV a0’ with ‘StateT s RV t0’
Expected type: [Integer] -> StateT s RV t0
Actual type: (->) ((->) [a0]) (RV a0)
• The function ‘lift’ is applied to two arguments,
but its type ‘([a0] -> RV a0) -> (->) ((->) [a0]) (RV a0)’
has only one
In a stmt of a 'do' block: prize <- lift uniform [1, 2, 3]
In the expression:
do { prize <- lift uniform [1, 2, ....];
return False }
