 Let's fire up GHCi:

 {{{
 $ ~/Software/ghc-8.2.0.20170507/bin/ghci
 GHCi, version 8.2.0.20170507: http://www.haskell.org/ghc/  :? for help
 Loaded GHCi configuration from /Users/rscott/.ghci
 λ> :set -XTypeApplications -fprint-explicit-foralls
 λ> import Data.Functor.Identity
 }}}

 I can use `TypeApplications` on `Identity` like so:

 {{{
 λ> Identity @Int 42
 Identity 42
 }}}

 But not if I try to use record syntax:

 {{{
 λ> Identity @Int { runIdentity = 42 }

 <interactive>:4:15: error: parse error on input ‘{’
 λ> (Identity @Int) { runIdentity = 42 }

 <interactive>:7:1: error:
     • Couldn't match expected type ‘Identity a0’
                   with actual type ‘Int -> Identity Int’
     • In the expression: (Identity @Int) {runIdentity = 42}
       In an equation for ‘it’: it = (Identity @Int) {runIdentity = 42}
 }}}
