Comment (by Herbert Valerio Riedel <hvr@…>):

 In [changeset:"9f4ca5afaccc8a397d8ee91b5423a9c2fcd151ce/ghc" 9f4ca5a/ghc]:
 {{{

 Associate ErrorCall pattern with ErrorCall type

 This way,

     import Control.Exception (ErrorCall(ErrorCall))

 or

     import Control.Exception (ErrorCall(..))

 work as expected, and import the `ErrorCall` compatibility pattern as
 well.

 When #5273 was implemented, it wasn't possible yet to associated
 patterns with their types (see #10653).
