+#' @title Run a function over a list of elements, distributing the
computations with Spark.
+#'
+#' @description
+#' Applies a function in a manner that is similar to doParallel or lapply
to elements of a list.
+#' The computations are distributed using Spark. It is conceptually the
same as the following code:
+#' unlist(lapply(list, func))
+#'
+#' @param list the list of elements
+#' @param func a function that takes one argument.
+#' @noRd

if this is an "exported" function then it should not have `@noRd` - please
see something like
[this](https://github.com/thunterdb/spark/blob/7264/R/pkg/R/SQLContext.R#L73)
