(setf
F)
to become defined; as such, if there is a such a definition
of a setf expander F, the function (setf
F)
can be fbound if and only if, by design or coincidence, a
function binding for (setf
F)
has been independently established.)
See the functions fboundp and symbol-function
.

expressions by the Lisp reader.

but there might be other, implementation-defined mechanisms for
invoking the file compiler.

the symbol :end

i.e., the position following the last element of the stream),
or a file position (denoting itself).

, which advances the display position
to the beginning of the next line (as if a newline had been typed, or
the function terpri
had been called)

Unlike newline, freshline is not a character.

Neither a use of a symbol as a function designator nor a
use of the function symbol-function
to extract the functional value
of a symbol is considered a functional evaluation.
