如果item在Lua数组中

Question

如何检查单词是否在数组中...例如：

fruits = { 'apple', 'banana' }
value = "carrot"
if not value == fruits then
  print ( value .. " is not a fruit" )
end

或类似的东西？我更喜欢纯粹的Lua。

直接的方式：

 g=e+f;   // will automatically construct a Derived from the result
          // and then execute `Derived`'s default `operator=` which 
          // will call `Base`'s `operator=`
