custom .DollarNames

[JanMarvin]

Do we gain anything from creating our custom .DollarNames autocompletion?

I was looking if we can implement a custom autocomplete for chained workbooks, but that did not work (at least not in the simple way I approached it).

#' @export
.DollarNames.wbWorkbook <- function(x, pattern = "") {
  grep(pattern, ls.str(x), value = TRUE)
}
