These are really good news!
However, the identifier IsString is probl

Automatic conversion to numeric types via fromInteger could be

This is really interesting. I love how the typechecker can resolve
1:0:1 (representing (1+x^2))
1 : 0 : 1
=> 1 : 0 : (fromInteger 1 :: [Integer])
=> 1 : 0 : (series (fromInteger 1 :: Integer))
=> 1 : 0 : (series 1)
=> 1 : 0 : 1 : repeat 0
