Well, almost.

GF reparses its objectbox arguments for parens and commas. With commas it 
makes init-messages. With parens it makes A_BINBUF atoms, which are nested 
lists (can you say « list atom » ?)

That's happening by default for all the classes, except that a class can 
turn off this behaviour.

Then there is another step.

a GF constructor that receives an A_BINBUF where a Grid* is declared, 
converts that binbuf to a grid, so that « 2 3 4 s # 5 6 7 » means « make a 
grid of shorts (s) of 2 by 3 by 4, and for all elements (in usual order), 
fill with 5,6,7,5,6,7,5,6,7,... ». (there are also simpler syntaxes for 
simpler cases)

GF used to also parse parens in messageboxes, but that is now gone. 
However, all grid-accepting inlets also accept list-messages and convert 
them to grids using the same syntax (except the parens).

Of course, GF does not modify the code of pd's messagebox class. (so
