Research direction
Start by reading the linked issue 4318 and tracing the existing symbol forms for .N, .SD, and .I in the data.table source. Identify the relevant tests for these symbols before determining the complete set of function-call forms; done means the supported forms have identical behavior and coverage confirms that equivalence.
Written by the indexing model from the issue text.
Description
so
.N()
.SD()
.I()
etc., will all have exactly the same meaning as their symbol forms
That would address https://github.com/Rdatatable/data.table/issues/4318
