\description{
  \code{as.function} is a generic function which is used to convert
  objects to functions.

  \code{as.function.default} works on a list \code{x}, which should contain the
  concatenation of a formal argument list and an expression or an
  object of mode \code{"\link{call}"} which will become the function body.
  The function will be defined in a specified environment, by default
  that of the caller.
}
\value{
  The desired function.
