根据文档如何变得更好的说法，return exit 之类的使用 c++的异常来实现的，很粗暴。

fn test1 v = (if v == true do return 1; 0)
fn test2 v = (if v == true do return 1)
fn test3 v = (if v == true then return 1 else return 0)
fn test4 v = (if v == true then 1 else 0)


(
	timeStart = timeStamp()
	for i = 1 to 100000 do test1 true
	format "test1-%
" (timeStamp() - timeStart)
	
	timeStart = timeStamp()
	for i = 1 to 100000 do test2 true
	format "test2-%
" (timeStamp() - timeStart)
	
	timeStart = timeStamp()
	for i = 1 to 100000 do test3 true
	format "test3-%
" (timeStamp() - timeStart)
	
	timeStart = timeStamp()
	for i = 1 to 100000 do test4 true
	format "test4-%
" (timeStamp() - timeStart)
	
	ok
)
