The problem here is not running the query (which works fine [1]), but the
gigantic return string. Right now, I do generate that entire string in
memory and then output it. This works fine for most queries, but your
example is a good percentage of Wikidata; think "uncompressed dump".

I'll have a look if I find some time; this is unlikely solved with a
5-minute-hack ;-)

In the meantime, either download and parse the latest dump (should only be
a few days old), or, depending on your usage, query WDQ live if possible.

Cheers,
Magnus
