OBJECT command arguments arity

[abrom]

The object command in its current form requires a subcommand and a key. Would there be any objections to a PR to update the function definition from

def object(*args)

to

def object(subcommand, key)

(with the appropriate changes to the function too of course!)

See:

https://github.com/redis/redis-rb/blob/master/lib/redis.rb#L549

Any variant from 2 arguments and redis returns an error.

See

https://github.com/antirez/redis/blob/unstable/src/object.c#L1014

Given all subcommands require c->argc == 3 ('OBJECT' + 2 arguments)

Downside would be the possibility for 'new' subcommands with optional/multiple arguments to be added and this requiring a further update. A safer middle ground might be something like:

def object(subcommand, *args)
  synchronize do |client|
    client.call([:object, subcommand] + args)
  end
end
