If the import of `.__T__[:base` is removed, cedta() returns FALSE. `[.data.table` then forwards the call to `[.data.frame`, which cannot handle data.table-style subsetting. This is warned about in <https://cran.r-project.org/package=data.table/vignettes/datatable-importing.html#data-table-in-imports-but-nothing-imported>; the 'do' package should have set the .datatable.aware = TRUE marker in its environment.
