Hi,

I think that in 3.8 Bazsi separated the states of values, so now there is a difference between nonexisting keys and keys that exist but their value is empty.

Hi,

How would you go about dropping keys with empty values?
Or more generally, conditionally select keys depending on their values?

I *think* something changed somewhere between 3.7 and 3.9 as I used to have
no values containing "", and now I do.

Cheers
