注：!!是Aegisub的内置脚本语言AUTO4特有的函数变量识别符，原生Lua本身跟Python一样也是用()进行函数识别的，但在针对具体的嵌入式开发应用场景时会发生变化。

!!的函数识别逻辑在Aegisub的kara-templater.lua下，代码为：

-- Function for evaluating expressions
local function expression_evaluator(expression)
f, err = loadstring(string.format("return (%s)", expression))
if (err) ~= nil then
aegisub.debug.out(2, "Error parsing expression: %s\nExpression producing error: %s\nTemplate with expression: %s\n\n", err, expression, template)
return "!" .. expression .. "!"
else
setfenv(f, tenv)
local res, val = pcall(f)
if res then
return val
else
aegisub.debug.out(2, "Runtime error in template expression: %s\nExpression producing error: %s\nTemplate with expression: %s\n\n", val, expression, template)
return "!" .. expression .. "!"
end
end
end
