nested groups fails to parse

hi @Mrmumu, first glad to see that you looked at CSLY.
for now nested groups are supported. And I have no plan to support it any soon as I son't see any usefull use case.
for your specific case the best solution is I guess :

Expr : OptinnalExpr ?
OptionnalExpr: STRING (COMMA [d] STRING)*

May I ask you what you arelooking at in CSLY ?
Are you planning to use it for any special purpose ?

The repeated error annoy me so I will look at it more precisely.

You mean are not supported I think.

Yes, I have solved it just like that:)

I was going to send an email to you actually, after I have finished the core of my project.

I am trying to implement XPath support for .net core. Right now, .net core only support XPath 1.0 but there is already XPath 3.1 recommendation on W3C. I'm trying to implement a lexer, parser for this grammar by using your project. There are other approaches but I would like to use the published grammar.

I have searched other lexer, parser approaches but your "embeddable" solution got me^^

Great project that tout have! I am happy that the "embeddedable" feature of CSLY got you. It was my main concern when I started it. Glad to see that I am not tottaly wrong.
