comment How to Negate a Pattern Test and Transform a List of Strings to a JSON array
+1 Unrelated to "negating a pattern test", but incidentally it is unnecessary to check listEmptyQ for the pattern {__String} (two underscores) since it will only match non-empty lists. The pattern {___String} (three underscores) will match both empty and non-empty lists.

comment Inserting symbols' definitions during read time of the code
@Kuba Yes, but testFunction as written is defined to use Test`Private`explicitvalue (I'm thinking defensively).

comment Inserting symbols' definitions during read time of the code
The example as written defines explicitvalue in the private part of the package. We need to reference it in the public part, e.g. add explicitvalue::usage = "..." before the private part.

comment 10.2 Dataset extraneous print using Transpose
@chris Personally, I think the patch is perfectly safe. But obviously WRI aren't going to support it.
