I also hope hyrise has this feature, it is usefull.

flex_lexer.l define the identifier is: ``` \"[^\"\n]+\" { // Crop the leading and trailing quote char yylval->sval = hsql::substr(yytext, 1, strlen(yytext)-1); return SQL_IDENTIFIER; } ``` change to ``` \"[^\"\n]+\" {...

I don't know whether this change is right,need your comment!

@mrks Hi,In your case,When you try to get `"test"` ’s type, you will get kExprColumnRef type;This is my problem.I think `"test"` type should be kExprLiteralString.

这里是保证效率，也就是跑分的时候证明这个协程库的上下文切换很快。事实上除了浮点数之外，信号也是没有保存。参考另外一个问题下开发者的回复来看，微信内部使用的协程库应该还有其他组件，并没有整理到开源版本中来。
