Hi,
I wrote lexer return (values (intern "{") (intern "{"))
but when using LR parser, the following error occurs.
I have red the code expanded by macro, and found that the second argument is
evaluated, which should be (intern "{").
If the lexer return (values '{ '{), it works.
So is there any way to use string to symbol function in lexer?
Thanks,
Haiwei
