Core lint error on record syntax update/pattern synonym
While on a flight I discovered some errors, if you load a file using record syntax for pattern synonyms:
module Foo where
pattern Pair{x, y} = (x, y)and load it with -dcore-lint:
$ ghci -dcore-lint -ignore-dot-ghci -XPatternSynonyms /tmp/Foo.hs
GHCi, version 8.1.20160419: http://www.haskell.org/ghc/ :? for help
[1 of 1] Compiling Foo ( /tmp/Foo.hs, interpreted )
Ok, modules loaded: Foo.
*Foo> (1, 2) { x = 10 }
*** Core Lint errors : in result of desugar expression ***
[...]full error message attached.
