Actually, as soon as I allowed myself to make an instance
variable, it didn't seem so bad.  Here's what I came up with:

def inspect
    to_s[0..-2].concat(" #{
        if defined?(@inspecting)
            "..."
        else
            begin
                @inspecting = true
                ... generate inspect contents here ...
            ensure
                remove_instance_variable(:@inspecting)
            end
        end
    }>")
end
