comment Using Merge[Identity] and Transpose on a Dataset
Up to v10.3, the data type information is used primarily for formatting the graphical representation of a Dataset or for performing a small number of proactive sanity checks upon a query. I have speculated that future releases may use the type information for data and/or algorithm optimization. I discuss the use of type information more fully in (87479), (89081) and (102696).

comment How to make CounterIncrement step in increments of 2
@Kuba Yes, the same CounterFunction must be used at all levels (a surprise to me). I have updated my answer to reflect that. Thanks.

comment A subtlety in Query
@halirutan The Query documentation says: Unless an operator is specifically recognized to be descending, it is assumed to be ascending. The descending operators are explicitly listed in the documentation. Apply is not on that list. Some ascending operators are discussed explicitly in the documentation, but usually because they behave differently as query operators than they do when used as normal functions.

comment File-name completion for custom functions
@Athanassios Yes, the method in (78935) enables autocompletion for option arguments, whereas the method here using specialArgFunctions.tr enables autocompletion for regular (non-option) arguments.

comment File-name completion for custom functions
@Athanassios specialArgFunctions.tr shows an example for a function with a hard-coded list of acceptable values for the first argument: "MyPlanetInfo"->{{"Mercury", "Venus", "Earth", "Mars", "Jupiter", "Uranus", "Neptune"}}
