hy缺乏基本的补全 vscode目前没法用我把hy改造成了可以自动reload 自动抓Uncaught exception的模式如果要取消这些行为需要加上flag 可以用于hy2py

-R
disable automatic insertion of reloading decorator
-T
disable toplevel try-except
-K
disable toplevel show stacktrace
-L
disable line-by-line try-except

一些未知的expression可能不允许被wrap到我们的macro里面需要被加入到黑名单已知的系列包括unpack-iterable之类的
