This syntax is documented.

Extract from the doc.


If ServerName={local,Name} the gen_server is registered locally as Name
using register/2. If ServerName=
{global,Name} the gen_server is registered globally as Name using
global:register_name/2. If no name is provided, the gen_server is not


Not providing a name is useful when you want to have a supervised child

Subject: Buglet in gen_server?


I've been using the emacs skeletons forever, and these do things such as:

gen_server:start_link({local, app}, app, [], []).

This syntax isn't documented in R9B, and is possibly deprecated, but the
interesting thing is that gen_server:call, and gen_server:start_link both
work, while gen_server:cast doesn't (and fails silently, the dangerous
little monster).

Is the ServerRef -> {local, app} syntax valid? deprecated? invalid?
