With the example above, one could perform canvas operations on the current canvas, ie: "this". So to answer your question, $! would be the equivalent to whatever name you supplied in [namecanvas], so it's type would be that of the canvas, an object type.
There's no atomtype for that.A_SYMBOL can only refer to a t_symbol (a normal symbol entry), which contains the receive-symbol info, so, a unique receive-symbol has to be registered if you want to use that. I mean, it's very doable and easy to add an extra pd_bind to each canvas, that would be "$0-canvas" or "$0-this" or whatever, but it's another feature, and it's one that you have to add before adding $!, because the value of $! depends on it... and then you don't really need $! because you can write $0-canvas instead.
A_POINTER can only point to "scalars" and elements of "array", not to any objects.
$-substitution can only ever mean something that could theoretically have come out of an object : I mean that $-substitution first makes a new message, and THEN another part of pd looks at what it means. So, $! can't be too special, it has to rest upon other features of pd.
