How to get nodes and ways by polygon in a single Overpass query

How can I get all the nodes and ways within some polygon in a single Overpass API query? For example, I can get all the ways like this;out;) and all the nodes like this.

But how might I combine these HTTP GET requests into a single query?

One Answer:

Take a look at the union operator:

https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Union

You will have to repeat the poly statement. Here's the poly example from the docs wrapped in a union:

(
  node(poly:"50.7 7.1 50.7 7.2 50.75 7.15");
  way(poly:"50.7 7.1 50.7 7.2 50.75 7.15");
  rel(poly:"50.7 7.1 50.7 7.2 50.75 7.15");
);

Thanks, yes, the wrapping parentheses were what I needed.
