The language syntax uses reverse Polish notation, which makes the order of operations unambiguous, but reading a program requires some practice, because one has to keep the layout of the stack in mind.
这种语言的语法使用逆波兰表示法 ,这就意味着不需要括号进行分割,但是因为需要记住堆栈结构,所以需要进行训练才能阅读这种程序。

Polish notation is compact and elegant, but rarely used in practice because it is hard for humans to read it.

Lukasiewicz introduced the 'Polish notation' which allowed expressions to be written unambiguously without the use of brackets and his studies were to form the basis for Tarski's work.

Reverse Polish Notation was developed in 1920 by Jan Lukasiewicz as a way to write a mathematical expression without using parentheses and brackets.
逆波兰式最早于1920年由 Jan Lukasiewicz 发明,作为一种无需括号的数学表达式。
Among his other contributions to computer science are the Reverse Polish Notation and related Shunting yard algorithm; the THE multiprogramming system, an important early example of structuring a system as a set of layers; Banker's algorithm; and the semaphore construct for coordinating multiple processors and programs.
