There's a big difference between putting a space after "#" and not putting 
a space. When one writes [# +], then "#" is the class name, and "+" is an 
argument ! This kind of argument is called a numop, and the same set of 
numops pops up in a bunch of different classes. It's thus much more 
flexible than having a class [#+] separate from [#-] and [#*] and so on, 
because then you can have [#draw_polygon +], [#draw_polygon -], and so on, 
where "#draw_polygon" is the class, and the type of compositing is an 

However, "see" is not a numop (NUMeric OPerator) in any way, so, it's 
actually part of a class name.

Spaces are ultra important, as they separate the classname from the $1, 
and that can happen anywhere in the use of pd, though you'd notice it more 
in GridFlow because of how GridFlow shifts some concept from "classness" 
or "argumentness".

[#see] is not an abstraction, it's an external.

Do you have error messages in the console at load time ?

I think that the exact names of every class are all written in the 
GridFlow Index, that you can find in the Help menu of Pd. From the 
GridFlow Index you'd do Right-Click Help if on an object itself, or plain 
Left-Click if it's only a link to the help file (links are underlined, 
soft borders, and a bright question mark).
