A name can be given to a function in one of two ways.
|
||
|
|
A <i>global name</i> can be given to a function by using the
|
||
|
|
<tt>defun</tt> construct.
|
||
|
|
A <i>local name</i> can be given to a function by using the
|
||
|
|
<tt>flet</tt> or
|
||
|
|
<tt>labels</tt> special form.
|
||
|
|
When a function is named, a lambda-expression is effectively
|
||
|
|
associated with that name
|
||
|
|
along with information about the entities that are lexically apparent
|
||
|
|
at that point.
|
||
|
|
If a symbol appears as the first element of a function-call form, then it
|
||
|
|
refers to the definition established by the innermost <tt>flet</tt> or <tt>labels</tt>
|
||
|
|
construct that textually contains the reference, or to the global
|
||
|
|
definition (if any) if there is no such containing construct.
