constant-declaration 常数声明
constant declaration section [计] 常数说明部分
constant differs from declaration 在记录常量中的域次序与说明不同
This means that the value of a local constant is undefined until the constant declaration statement is reached and that a local variable is undefined until the variable is assigned to in the function.
这就意味着在到达常数声明语句前局部常数值是未定义的,在函数中分配变量前局部变量是未定义的。
Also as the name says, implicitly typed local variable, you cannot use var for field declaration or constant variables, therefore following declarations will both produce a compiler error.
故名思意,“隐式类型局部变量”将无法用于域变量或常量的声明中,否则将导致编译错误。
