Fairly said, I'm sure Guillaume would object - given that it's not
exactly pure in that sense.
As to why the error happens for copy-paste, from what I can see this
removes important linefeeds (if you copy-paste from the same page,
you'll see this when you paste into a standard ASCII editor, eg
notepad); the first two lines join and the Groovy parser tries to
process "def xwiki  def context" as one instruction instead of two
instructions.
The only difference now is that the ";" forces the parser to start a new
instruction, so "def xwiki;  def context" is processed as two separate
instructions.
IIRC, some platforms treat linefeed differently, so this may not even be
a problem if you use *nix to copy the text.
Perhaps something could be done to make the {code} put hard breaks
between lines though?  Then this change (or even the warning) wouldn't
be needed.

Hi Brandon,

 after
 each line (it's only the first two lines of the class that has this
 problem for the example).
 I'll add some text to the example to highlight this. 
I see you've modified the page on 
xwiki.org, cool. However I know for
sure that Groovy purists will not like the change as they consider that
Groovy code shouldn't have any semicolon (";") at all. I know Guillaume
Laforge wouldn't like it for example...
Thus I think we shouldn't add them, especially as they're not necessary.
I don't understand why a copy paste wouldn't work. In any case I'd
prefer a warning rather than having to make the code less good.
WDYT?
Thanks

 Hi
 I tried to follow the Groovy Tutorial given in the developer guide.
 But
 I couldn't make it run.

 Instantiating groovy class from velocity threw the foll error :

 Instantiating groovy from groovy resulted in the foll error :

 (While creating the class I have assigned programming rights to the
 user who made the class.) What am I doing wrong.
 Thanks and Regards
