I'm not very much concerned with methods that accept veryveryverymany
arguments (except in the case of undifferentiated A_GIMME args, a la [list
append] and such). The readability aspect I had in mind is that the
declaration of methods should be formattable as a nice table that lists
you all the methods of a class in a way that does fit on a page. You
*could* use tools that would generate the big picture from a more
verbosely written code, but it's easier to get the big picture for free as
you're writing the code (or reading it).

I think that atomtypes are very few and will most likely stay rather few,
so it's easy to remember the abbreviations of them all, and we'll never
come close to run out of letters of the alphabet, unless we change the
typing paradigm completely, but that would require a completely new API
anyway.
Note: I don't even know whether it will be possible to add A_STRING and
A_LISTPTR, because reference-counting would require that t_atom gets a
constructor and a destructor, which would be a change to Pd's external API
which wouldn't be backwards-compatible.
