Coerce polynom or polylist objects to function.
polynom objects are represented as functions,

Not currently used.
polynom objects are already stored as functions,
as.function.polynom is rarely needed and may be replaced by
unclass. An explicit call to
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
R function implementing the evaluation.
