I've have changed the first source for the Perl/Undecidability discussion from it's original version in on a bulletin board, which has many flaws of presentation, to an later, carefully rewritten version which appeared in an edited journal. The new source in more in keeping with WP:Verifiability, and is just plain better all around. In the interests of full disclosure, I am the author of both. Since the new title presents no issues when taken literally, I also removed the comment. —Preceding unsigned comment added by Jeffreykegler (talk • contribs) 17:37, 15 April 2010 (UTC)
The example highlights "str" differently than "children" because "str" is a keyword. However, I would argue that this is not a syntactic difference, it concerns semantics. So the "syntax highlighting" is actually more than that. Does anyone agree? How can we explain this? --Ysangkok (talk) 00:38, 25 December 2014 (UTC)
