+\description{
+\itemize{
+\item \code{\link[rlang]{sym}()} creates a symbol from a string and
+\code{\link[rlang:sym]{syms}()} creates a list of symbols from a
+character vector.
+\item \code{\link[rlang:nse-defuse]{enquo}()} and
+\code{\link[rlang:nse-defuse]{enquos}()} delay the execution of one or
+several function arguments. \code{enquo()} returns a single quoted
+expression, which is like a blueprint for the delayed computation.
+\code{enquos()} returns a list of such quoted expressions.
+\item \code{\link[rlang:nse-defuse]{expr}()} quotes a new expression \emph{locally}. It
+is mostly useful to build new expressions around arguments
+captured with \code{\link[=enquo]{enquo()}} or \code{\link[=enquos]{enquos()}}:
+\code{expr(mean(!!enquo(arg), na.rm = TRUE))}.
+\item \code{\link[rlang]{as_name}()} transforms a quoted variable name
+into a string. Supplying something else than a quoted variable
+name is an error.
+
+That's unlike \code{\link[rlang]{as_label}()} which also returns
+a single string but supports any kind of R object as input,
+including quoted function calls and vectors. Its purpose is to
+summarise that object into a single label. That label is often
+suitable as a default name.
+
+If you don't know what a quoted expression contains (for instance
+expressions captured with \code{enquo()} could be a variable
+name, a call to a function, or an unquoted constant), then use
+\code{as_label()}. If you know you have quoted a simple variable
+name, or would like to enforce this, use \code{as_name()}.
