One of the major features of TurtleScript (Logo) is the ability to translate the commands to suit the native language of the student . Thus, I think that opting out script blocks from translation is somewhat wrong.
Ok, well, in it goes then :-)
Maybe we should consider rewriting the wiki-source in the original to something sensible, though. I wouldn't like to work with it the way it looks now. I guess it's automatically generated HTML.
It would be easy to copy and paste the displayed code examples into an Input template, but we'd lose syntax highlighting. The <syntaxhighlight> tag doesn't seem support Logo. Could we use highlighting for some other language instead?
