I didn't know that pyregion is not a complete DS9 region parser and I think wasn't part of the DS9 grammar / parse discussions last year (or forgot). OK, fine...

Maybe @nden or @astrofrog or someone that knows `astropy.wcs` well can comment: In the example given by @leejjoon in the comment above this one, is the `nan` output expected /...

Is this a blocker for a pyregion 2.0 release or can it be moved to 2.1? @astrofrog or @keflavich - Could you please have a look at the example by...
