It's a very worthwhile simplification, because it completely gets rid of the `getProxies` stuff that was eating all the time before. Alas, compiling W2 is still non-linear. Here's the allocation by the stage-2 compiler * 50 fields: 1.01 Gbyte * 100 fields: 2.98 Gbyte * 200 fields: 9.64 Gbyte This is after including the improvements to the derived `Read` code in #7450. So something is still wrong. Need to do some profilling to find out. There are some very deeply nested lambdas, which lead to SRTs of ever- increasing size, so there is definitely a quadratic effect there.

Comment:
Here's an example of the sort of context this comes up in:
{{{
module T7542 where
import Unsafe.Coerce
newtype Id a = MkId { unId :: a }
-- Think of `mapped` as `mapM`, but restricted to Id (we could make it
work
-- with any Functor, rather than just []). `over` takes the Id wrappers
back
-- off. The goal is to make it easy to compose mapped with other functions
of
-- the same form. The wrapper should be free because it's just newtype
noise.
mapped1 :: (a - Id b) - [a] - Id [b]
mapped1 f = MkId . map (unId . f)
over1 :: ((a - Id b) - s - Id t) - (a - b) - s - t
over1 l f = unId . l (MkId . f)
map1 :: (a - b) - [a] - [b]
map1 f xs = over1 mapped1 f xs
-- Core: map1 = \f xs - map (\x - f x) xs
-- over1 mapped1 = unId . MkId . map (unId . MkId . f)
-- ~ map
-- However, if f = ⊥, unId . MkId . f /= f!
-- Therefore `over1 mapped1` must turn into \f - map (\x - f x)
-- We can't expect GHC to compile it to `map` because it has different
strictness.
-- Let's define strict versions of (MkId .) and (unId .):
mkIdDot2 :: (a - b) - a - Id b
mkIdDot2 f = f `seq` \x - MkId (f x)
unIdDot2 :: (a - Id b) - a - b
unIdDot2 f = f `seq` \x - unId (f x)
mapped2 :: (a - Id b) - [a] - Id [b]
mapped2 f = mkIdDot2 (map (unIdDot2 f))
over2 :: ((a - Id b) - s - Id t) - (a - b) - s - t
over2 l f = unIdDot2 (l (mkIdDot2 f))
map2 :: (a - b) - [a] - [b]
map2 f xs = over2 mapped2 f xs
-- map2 should have the same semantics as map. But the Core isn't the
same:
-- Without -fpedantic-bottoms: map2 = \f xs - map (\e - f e) xs
-- With -fpedantic-bottoms:
-- map2 = \f xs - map (case f of g { __DEFAULT - \x - g x }) xs
-- Ideally, (case f of g { __DEFAULT - \x - g x }) would simply be f.
-- Let's try manually telling GHC that our newtype compositions are
coercions:
-- (Ideally, this is what mkIdDot2 and unIdDot2 would compile into.)
mkIdDot3 :: (a - b) - a - Id b
mkIdDot3 = unsafeCoerce
unIdDot3 :: (a - Id b) - a - b
unIdDot3 = unsafeCoerce
-- (Note: Due to #7398, we couldn't define a strict composition operator
and
-- rely on RULES to turn (MkId `dot`) into unsafeCoerce -- the `MkId`
itself
-- gets turned into a coercion before any RULES have a chance to fire.)
mapped3 :: (a - Id b) - [a] - Id [b]
mapped3 f = mkIdDot3 (map (unIdDot3 f))
over3 :: ((a - Id b) - s - Id t) - (a - b) - s - t
over3 l f = unIdDot3 (l (mkIdDot3 f))
map3 :: (a - b) - [a] - [b]
map3 f xs = over3 mapped3 f xs
-- Core: map3 = map
