Consider that you can use a tuple generated elsewhere for a UDA:
[tp] void foo();
where tp is a tuple. You can even grab the attributes from another symbol, turn
them into a tuple, and apply the tuple as an attribute to a new symbol. Tuples
can, of course, be sliced and concatenated.
In other words, by using tuples, you can "encapsulate" what the attributes
expand to in the same way you can change target code by changing the definition
of user defined types.
