Comment (by Simon Peyton Jones <simonpj@…>):

 In [changeset:"cf0a55d76cf945a97fc229b77d6e6177fb14125d/ghc"]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="cf0a55d76cf945a97fc229b77d6e6177fb14125d"
 For :info, return all matching Names, rather than complaining about
 ambiguity

 This fixes Trac #9881, and gives more helpful output in the case of
 ambiguity.
 Certainly more helpful than the positively-misleading error we get right
 now.
