但是,数字和字符串确实得到automatically coerced in a few cases：

Lua provides automatic conversion between string and number values at run time. Any arithmetic operation applied to a string tries to convert this string to a number,following the rules of the Lua lexer. (The string may have leading and trailing spaces and a sign.) Conversely,whenever a number is used where a string is expected,the number is converted to a string,in a reasonable format

从而：

local x,y,z = "3","8","11"
print(x+y,z)  --> 11   11
print(x+y==z) --> false
print(x>z)    --> true

我不想要这个.如何重新编译Lua解释器以删除所有自动转换？

我更愿意：

print(x+y)    --> error: attempt to perform arithmetic on a string value
print(x>1)    --> error: attempt to compare number with string
print(x..1)   --> error: attempt to concatenate a number value
