comment CountryData vs EntityProperty: why do different data access methods produce different results?
The case of CountryData is discussed in both responses to Finding out all undocumented values for “Properties” in XxxData functions. It is not clear to me whether or not the present question should be considered a duplicate.

comment How to ValueQ a symbol, constructing the symbol name from strings?
You need to use ToExpression["box`" <> name, InputForm, ValueQ]. This question is essentially a duplicate of How can I test properties of a symbol from the string name without the symbol completely evaluating. Voting to close.

comment ToExpression processing errors
I added an example of what I meant by "more elaborate error-handling". This is probably about as bullet-proof as we can get in high-level Mathematica code, without access to the internal C++ parsing code.

comment Operating on a dataset named “data” triggers an error message
The result of the GroupBy operation is actually correct. The message data::shdw is a known V10.2 bug discussed in (88393). See that question for a work-around. Voting to close as a duplicate.

comment Removing elements from a nested list based on their global count
The pronunciation of (##&[]) cannot be uttered in polite company. It is a rather harsh colloquial synonym for Nothing. ;)

comment Why this shadowing when dealing with a dataset?
This is essentially the same problem as reported in Streaming`LazyList`Testing may have a leak. Voting to close as a duplicate.

comment Windows command line arguments, stdin & stdout
@William Streams named "stdout" and "stderr" are available, e.g. WriteString["stderr", "bad news!"]. As to re-using a session using only streams and strings, the only approach that comes to mind at the moment is to implement a Telnet-like protocol where Mathematica and the other process take turns sending commands and responses back and forth. MathLink would give complete fine-grained control but would take more effort to set up.
