Since functions and actions are first-class, is it possible for an entity variable to hold a function? Historically that was not the case; entity variables could only be flags, counters, trails, or literals.
A corollary to that, if the answer is true. Can a function be defined in a postlude and assigned directly to an entity variable?
(This is a question from the CS 462 mailing list .)
否。实体变量只能包含字符串和数字,数组,结构及其任何组合。
