Since `polynom`

objects are represented as functions,
`as.function.polynom`

simply removes the `class`

attribute.
The function `as.function.polylist`

produces allows all
polynomials on the list to be evaluated simultaneously at the same
argument value.

Since `polynom`

objects are already stored as functions,
`as.function.polynom`

is rarely needed and may be replaced by
`unclass`

. An explicit call to `as.function.polynom`

,
however, will generate a slightly faster version of the function as an
unrooled loop, and does allow the user to specify a different name for
the formal argument to be used.

Since arithmetic on polynomials is provided, both of these
functions may be evaluated at a `polynom`

object as well as a
numeric argument.

An `R`

function implementing the evaluation.
