Oddly, so far as I can figure out, the regex in the first panel is wrong, in that it doesn't match the second Star Wars movie at all.

| − | '''Regex golf''' (c.f. {{w|Perl golf}}) is a programming competition / is a pastime of finding regular expression that matches one set of strings while matching none of the other set.

| − | The title text isn't exactly true... I haven't tried everything, but that regex doesn't match "gerald ford" at all. [[Special:Contributions/199.27.128.109|199.27.128.109]] 11:23, 6 January 2014 (UTC)

| − | Inspired by regex.alf.nu, a reader built a page where the objective is to make a regular expression to match all Star Wars and no Star Trek: http://zegnat.github.io/xkcd1313/. [[Special:Contributions/173.245.53.127|173.245.53.127]] 14:00, 6 January 2014 (UTC)

| − | I added a list of all US elected presidents and the part of the title regex they match. I used a python script to generate it, with input from [http://http://en.wikipedia.org/wiki/List_of_United_States_presidential_candidates here], then I removed all presidents that do not match after finding they really weren't elected. There may still be superflous ones, that weren't elected but do match the regex, please check. [[Special:Contributions/173.245.49.64|173.245.49.64]] 14:29, 6 January 2014 (UTC)

Is it a reference to regexes in some way or could it be something like that there are infinite problems in life, even when not doing (Meta-)*-Regexes? --[[Special:Contributions/173.245.53.199|173.245.53.199]] 20:32, 6 January 2014 (UTC)

| − | "Note that if one included the animated film “Star Wars: The Clone Wars” it would be matched by “ [tn]”."
| |
| − | - I don't see how this is true, since the T is at the beginning of the subtitle. If this matched, then surely so would all of the original series Star Trek films. {{unsigned ip|141.101.99.41}}

| |
| − | This isn't true either - there was already a presidential loser whose surname was Clinton (DeWitt Clinton, 1812). So presumably Hillary Clinton is likewise not considered in terms of regex eligibility. --[[Special:Contributions/172.68.132.59|172.68.132.59]] 23:05, 13 April 2017 (UTC)

| − | [Megan is sitting at a laptop. Cueball is standing behind her.]

| |
| − | Meta-meta-regex golf:

| |
| − | Megan: ...But I lost my code, so I'm grepping for files that look like regex golf solvers.

| − |
| |
| − | ...And beyond:
| |
| − |
| |
| − | Megan: Really, this is all /(meta-)*regex golf/.
| |
| − |
| |
| − | Megan: No, I had those already.
