drvfail012.hs:5:33: error:
• Could not deduce (Eq (Ego a))
arising from the 'deriving' clause of a data type declaration
from the context: Ord a
bound by the deriving clause for ‘Ord (Ego a)’
at drvfail012.hs:5:33-35
Possible fix:
use a standalone 'deriving instance' declaration,
so you can specify the instance context yourself
• When deriving the instance for (Ord (Ego a))
