“盲人摸象”的故事用来形容这一情况似乎很合适。还可以放心地将 FP 与“命令编程”(使用例如 C、Pascal、C++、Java、Perl、Awk、TCL 以及其它大多数语言所执行的操作,至少是在很大程度上)进行对比。 从个人角度来说,我会将函数编程粗略地描绘为至少具有以下几个特征。称得上函数性的语言使这些事情变得简单,而使其...

不幸的是,即使是函数程序员他们自己也很难对 FP 究竟是什么有个一致的认识。“盲人摸象”的故事用来形容这一情况似乎很合适。还可以放心地将 FP 与“命令编程”(使用例如 C、Pascal、C++、Java、Perl、Awk、TCL 以及其它大多数语言所执行的操作,至少是在很大程度上)进行对比。
