(01:01:10 PM) James_F: subbu: <ref> in a <ref> is invalid.
(01:01:20 PM) James_F: As is {{#tag:ref}} in a <ref>?
(01:01:35 PM) subbu: James_F, yes, that is what i meant
(01:01:38 PM) James_F: Or something hideously stupid.
(01:01:43 PM) James_F: Yay wikitext. :-(
(01:01:51 PM) subbu: but, yes,you are right ... <ref> in <ref> is invalid.

(01:08:37 PM) cscott-free: i should add that to my list of "101 crazy ways to escape wikitext"
(01:09:03 PM) marcoil: only 101?
(01:09:05 PM) cscott-free: <nowiki>, {{!}}, {{#tag:ref}}, &#xx; %zz  i'm sure I'm missing some.
(01:09:34 PM) subbu: there are multiple of the {{!}} type templates
(01:09:43 PM) subbu: {{=}} i think to around having to add nowikis

Magic Links should be removed from the parser.

unclosed list items

{{echo|style="red"}} <-- this is a template parameter.
Use {{echo|style{{=}}"red"}} (yuck) to get the literal.

[<nowiki/>[[sic]]] produces a wikilink to "sic" inside of square brackets.
  -- CSA really?

has:
{{#arrayprint:colors||@@@@|<nowiki/>
* length of @@@@: {{#len:@@@@}}
}}

from Krinkle:
(01:17:42 PM) Krinkle: I noticed that using || in template values tends to produce <nowiki> instead of {{!}}
(01:18:08 PM) Krinkle: Does parsoid ever produce {{!}}?
(01:20:46 PM) Krinkle: Funny stuff happens when you feed that to {{#tag:}}, e.g. https://www.mediawiki.org/w/index.php?title=Project:Sandbox&oldid=1702766&veaction=edit
(01:21:09 PM) Krinkle: edit the phpi example call, change {{!}} back to  II in the inspector and save. it'll become <nowiki>
(01:22:10 PM) cscott-free: Krinkle: that sounds like an example for my "crazy wikitext escapes" file.
(01:22:12 PM) Krinkle: Oh, only in the preview. the saved text uses {{!}}
(01:22:21 PM) Krinkle: interesting

(05:45:47 PM) cscott-free: the original WAT talk was like: (1) present code (wikitext) on slide, (2) present evaluation of that code (rendering of that wikitext)
(05:46:15 PM) cscott-free: i think this talk would have to be the reverse: (1) present desired output, (2) present wikitext generating that output.

(05:46:07 PM) gwicke: cscott: you should include at least one example that only works because tidy breaks things in different ways that MW does
(05:46:13 PM) gwicke: *than
(05:46:31 PM) cscott-free: gwicke: can you give an example?
(05:46:51 PM) gwicke: empty list items being stripped could be one, but that's relatively lame
(05:46:56 PM) cscott-free: "tidy eliminates empty elements" is the most obvious one i can think of, but it's not really WATish
(05:46:57 PM) arlolra: gwicke: preferable a few examples, formatted as a talk

(06:03:06 PM) gwicke: templates would be fun of course
(06:05:10 PM) gwicke: although the best examples might now be lua modules
(06:05:58 PM) gwicke: https://en.wikipedia.org/wiki/Wikipedia:Advanced_template_coding
(06:06:18 PM) cscott-free: i don't yet have any examples of crazy escapes required by lua modules, except maybe {{#arrayprint}} ?
(06:06:39 PM) gwicke: oh, also the self-replicating subst
