I swear, this language.

But:

    $ perl -MJSON::PP=encode_json -E 'say encode_json(1,2)'
    Too many arguments for JSON::PP::encode_json at -e line 1, near "2)
    $ perl -MJSON::PP=encode_json -E 'say encode_json((1,2))'
    2

So what's going on there? (Google is not very helpful for these sorts
of Perl problems; I don't even know how to describe this.)

I had to revert the test for unrelated reasons [1], so if this is
indeed guaranteed to be safe then I can make the change in my next
attempt.

Thanks!
