Getting type parameter of a weak type in a macro implementation

Question

In a macro impl[A: c.WeakTypeTag], if I find that c.weakTypeOf[A] <:< typeOf[Option[Any]], how do I get the type parameter of the Option? E.g., when A is Option[String], I need to find String.

Same problem as here:

c.asInstanceOf[TypeRefApi].args.head
