Strange import from data.table

importFrom(data.table,`.__T__[:base`)

This is a very unusual object to import in your NAMESPACE -- as far as I can tell, these are an implementation detail / not to be relied upon.

We recently encountered this when removing import(methods) from data.table's own NAMESPACE:

Rdatatable/data.table#6000

Could you elaborate on why this entry is needed?

This message: https://stat.ethz.ch/pipermail/r-package-devel/2024q1/010584.html describes the issue, and suggests a better solution: insert code

.datatable.aware = TRUE

somewhere in the source of your package (outside any function). There's no need to export this value, it just needs to be visible to any function that uses data.table syntax when subsetting.
