In my attempt to venture in the realm of LaTeX3 coding, I was wondering if a list of answers, in LaTeX3, can be made? That is, a list of links to answer in which users here at TeX.SX have used such coding. This will enable me to look at this post and look at samples instead of searching for examples everywhere on the website.

In almost all of them there is \ExplSyntaxOn – egreg Feb 2 '13 at 20:24
@egreg Hmmmm really. I know you personally like to add your flavor of LaTeX 3 programming. I am looking for questions and answers in terms of implementation and usage of LaTeX 3. I am good at learning by example. – azetina Feb 2 '13 at 20:28
LaTeX3 is out? Since when? How come I didn't get the memo? – cryptic0 Feb 2 '13 at 20:52
@cryptic0 The question is really about expl3, the programming layer, which is available and usable – Joseph Wright Feb 2 '13 at 20:58
The LaTeX3 project was announced at conference in Prague in 1992. I was there. This is more than two decades. But users are using a provisional release (called LaTeX2e) still. And here are many of history problems (like cm-fix.sty, for example) -- they are as prisoner ball in LaTeX2e. Despite this users don't need any changes. – wipet May 8 at 4:41

Almost all LaTeX3 answers will use expl3 or xparse packages, or as egreg says use \ExplSyntaxOn (which is the LaTeX3 analogue of \makeatletter to allow package code in the preamble) thus a link such as

will show most of the things that you wish to find.

or of course those explicitly tagged:

I will look into it. – azetina Feb 2 '13 at 20:56
Sorry to dredge this up, but does this mean that \ExplSyntaxOn is similarly implicit in package/class files? – Sean Allred Jul 9 '13 at 23:39
@SeanAllred It means it probably would be implicit if there were a latex3 package loading mechanism, but there isn't so far:-) – David Carlisle Jul 9 '13 at 23:47

Though the question was asked long back, for anyone who views this and would like to learn LaTeX3 Programming, Programming LaTeX3: Creating functions provides a really good introduction with number of examples and the documentation can be used for further understanding and exploration.
