Multiple values for a page param

Now I can only add page params by one and it bothers:

source1: "reddit"
source2: "book"

I’d like to arrange page params like taxonomies:

tags: ["hello", "world"]
sources: ["reddit", "book"]

Is it possible to set a range of values for params this way?

Yes, what’s stopping you from doing that?

The page params are completely flexible; just design your templates to match your expectations.
