functional value: n.
1. (of a function name N in an environment E)
The value of the binding named N
in the function namespace for environment E;
that is, the contents of the function cell named N in
2. (of an fbound symbol S)
the contents of the symbol's function cell; that is,
the value of the binding named S
in the function namespace of the global environment.
(A name that is a macro name in the global environment
or is a special operator might or might not be fbound.
But if S is such a name and is fbound, the specific
nature of its functional value is implementation-dependent;
in particular, it might or might not be a function.)
further compilation: n.
implementation-dependent compilation beyond minimal compilation.
Further compilation is permitted to take place at run time.
Block compilation and generation of machine-specific instructions
are examples of further compilation.
