[info objects] trouble

I'm having trouble to use the itcl-extended info commands.
See below, what is wrong?

% info patchlevel
8.4.8
(bin) 2 % package require Itcl
3.3
(bin) 3 % namespace import itcl::*
(bin) 4 % info objects
bad option "objects": must be args, body, cmdcount, commands, complete,
default, exists, functions, globals, hostname, level, library, loaded,
locals, nameofexecutable, patchlevel, procs, script, sharedlibextension,
tclversion, or vars
