Here's a quick Pd-l2ork patch to automate the process:

[bang(
|
|     [r break]
|     |
[until]
|
[f]x[+ 1]
|
[classinfo objectmaker]
|
[route bang]
|          |
[s break]  |
            [add2 $1(
            |
            [ (

Which fills the message box with this:

Some of these-- like "preset_node" and "draw"-- are in Pd-l2ork but not 
Pd Vanilla.

Others are just aliases, or "creator" names.  To filter them I drip that 
list through another [classinfo].  So these aren't actually class names:

switch~ q8_sqrt~ q8_rsqrt~ r~ s~ del v fswap t sel r s b f i 
filledellipse drawellipse filledrectangle drawrectangle filledcurve 
filledpolygon drawcurve outlet~ inlet~ vslider toggle my_numbox 
my_canvas hslider radiobutton radiobut rdb group table group page

***

That leaves 216, but that's probably not accurate because the 
"objectmaker" class doesn't have methods for every loaded Pd class. Ones 
like "message" and others which can't be created in an object box don't 
appear with my patch.  For a comprehensive list of loaded classes I'd 
need to step through Pd-l2ork's class table.  That might be nice to add 
to [pdinfo] (which again is only available in Pd-l2ork).

But again, this won't tell you about classes that are _potentially_ 
loadable by Pd-l2ork/Pd-extended which haven't been loaded yet.  For 
that you'd probably need to search all the paths Pd searches and look 
for binaries with the extension for your particular OS (on GNU/Linux I 
believe it's .pd_linux).  Then try loading all of those libraries, then 
step through the class table (which again only exists in Pd-l2ork) and 
get the tally.

When I code up a method to query the class table, I'll make a patch to 
load every binary in every search path of Pd.  That should give a 
definitive answer on the total "loadable" classes in Pd-l2ork (which is 
probably close to Pd-extended).
