tcfail046.hs:10:50: error:
• No instance for (Eq (Process a))
arising from the first field of ‘Do’ (type ‘Process a’)
(maybe you haven't applied a function to enough arguments?)
Possible fix:
use a standalone 'deriving instance' declaration,
so you can specify the instance context yourself
• When deriving the instance for (Eq (Continuation a))
tcfail046.hs:22:25: error:
• Could not deduce (Eq (Process a))
arising from the first field of ‘Create’ (type ‘Process a’)
from the context: Eq a
bound by the deriving clause for ‘Eq (Message a)’
