funcall造句

• :: : In Scheme there is no funcall keyword.
• The standard FUNCALL function is not generic; it only takes function objects.
• Conversely, to call a function passed in such a way, one would use the funcall operator on the argument.
• We have " almost " the same syntax : FUNCTOR-CALL instead of FUNCALL . Some Lisps provide " funcallable " objects as a simple extension.
• Function bindings cannot be dynamically scoped using flet ( which only provides lexically scoped function bindings ), but function objects ( a first-level object in Common Lisp ) can be assigned to dynamically scoped variables, bound using let in dynamic scope, then called using funcall or APPLY.
