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

 \code{as.function.default} works on a list, which should contain the
 concatenation of a formal argument list and an expression or an 
 object of mode "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.

\note{ The \code{alist} function is handy for the construction of
argument lists, etc. }
