Can't parse ''(*) in GHC HEAD

I can't build the reflection library on GHC HEAD since the ''(*) Template Haskell name no longer parses. Here is a smaller example which compares GHC 8.4.3 (what should happens) with HEAD (which fails):

$ /opt/ghc/8.4.3/bin/ghci -XTemplateHaskell
GHCi, version 8.4.3: http://www.haskell.org/ghc/  :? for help
Loaded GHCi configuration from /home/rgscott/.ghci
λ> import GHC.TypeNats
λ> ''(*)
GHC.TypeNats.*

$ ~/Software/ghc/inplace/bin/ghc-stage2 --interactive -XTemplateHaskell 
GHCi, version 8.5.20180617: http://www.haskell.org/ghc/  :? for help
Loaded GHCi configuration from /home/rgscott/.ghci
λ> import GHC.TypeNats
λ> ''(*)

<interactive>:2:4: error: parse error on input ‘*’

int-index, I believe this was caused by your commit d650729f (Embrace -XTypeInType, add -XStarIsType). Do you know what is going on here?
