parser : the API annotation on opt_sig is being discarded
The opt_sig production is defined as
opt_sig :: { ([AddAnn],Maybe (LHsType RdrName)) }
: {- empty -} { ([],Nothing) }
| '::' sigtype { ([mj AnnDcolon $1],Just $2) }It is used in the alt and decl_no_th productions, but neither of them add the returned annotations.
