<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: grid-line custom identifier auto?<br>
&lt;dael> github: https://github.com/w3c/csswg-drafts/issues/2856<br>
&lt;dael> Rossen_: eric brought this and fantasai you put this on the agenda<br>
&lt;dael> fantasai: There was an issue against grid asking if the ID auto should be excluded from the places where we use custom ident to rep. named lined. Auto has a special meaning it doesn't resolve to a named line. We exclude span keyword, but not auto.<br>
&lt;dael> fantasai: Question if we should exclude auto in places we exclude span<br>
&lt;dael> Rossen_: I wouldn't put span and auto in same cat. for this behavior. span is forward looking directive and auto is a applied to a single item<br>
&lt;dael> fantasai: You cannot have...if you named a line auto you're just going to have trouble, esp. in level 2 where you can combine auto with a custom ident. You can see the grammar in the issue. If a custom ident can include auto you can write auto1 and have that resolve. I'm not sure allowing that is helpful<br>
&lt;dael> fantasai: Where we have span custom ident we're planning to add auto as a similar pattern. That's a grid 2 issue<br>
&lt;fantasai> https://github.com/w3c/csswg-drafts/issues/796#issuecomment-385547068<br>
&lt;dael> Rossen_: I see your point<br>
&lt;dael> Rossen_: I can live with it<br>
&lt;dael> Rossen_: Anyone from mozilla that's close to grid impl. dbaron do you have an opinion?<br>
&lt;dael> dbaron: No opinion. Have to ask Mats<br>
&lt;dael> Rossen_: It's only our impl that allow auto<br>
&lt;dael> fantasai: I think chances of people naming a line auto is pretty much 0 unless you're a QA person<br>
&lt;dael> Rossen_: How did we end up removing span but not auto?<br>
&lt;dael> fantasai: Don't know. I think there's some syntactic construct where one was ambig. It said span and a custom ident you could do and you want to know that you are consuming a custom ident or the span up front. If you write span span is it a keyword or an ident. So we prob did for parsing<br>
&lt;dael> Rossen_: We allow span int and span custom ident<br>
&lt;dael> fantasai: Yes and auto custom ident will be in L2<br>
&lt;dael> Rossen_: Okay, I'm okay with proposed change<br>
&lt;dael> Rossen_: Any other opinions? Or do we try to resolve?<br>
&lt;fantasai> s/auto custom ident/auto &lt;custom-ident>/<br>
&lt;dael> Rossen_: Objections to dropping auto from grid line syntax?<br>
&lt;dael> RESOLVED: drop auto from grid line syntax<br>
