Hello,

In R13B02, pg2:get_closest_pid/1 has an incorrect spec. It says:
(pg2.erl, line 144)

-spec get_closest_pid(term()) -> pid() | {'no_process', term()}
| {'no_such_group', term()}.

It should be:

-spec get_closest_pid(term()) -> pid() | {'error', {'no_process', term
()}}
| {'error', {'no_such_group',
term()}}.

Paul

PS: I wish there was (I knew ?) a way dialyzer could figure these
cases out.

Thanks for reporting this one. It will be fixed in the upcoming release.
