What about a list (GiNaC::lst) of relational objects, e.g.

DECLARE_FUNCTION_2P(foo)
static ex eval_foo(const ex& x, const ex& y)
{
	lst l;
	l = x == x + y/2, y == cos(x);
	return l;
}
REGISTER_FUNCTION(foo, eval_func(eval_foo))

Exactly, since most operations with expressions do not make any sense
for associative arrays. So I wonder why you want to treat associative
arrays as expressions.


Best regards,
 Alexei
