See my previous reply to your question. $1 is a built-in global and will not be
"locally scoped"
unless you declare it as such.

Pseudo-code:
if "x is true" ? do this : else do this;
same as:
if ( "x is true" )
{
do this
}
else
{
do this instead
}
I tend to use trinary operators a lot. But don't use them if you don't like them. :)

CGI.pm does not filter anything for you (well, you can set the $CGI::POST_MAX variable
to limit
posting size, but that's not quite what you were asking). There has been some
additional
discussion of security regarding this lesson in my course. You can find this
dicussion at
http://www.perlmonks.org/index.pl?node_id=136655 and at
http://www.perlmonks.org/index.pl?node_id=136864. These get a little deep, though.

Someone asked me how to count to 10 in Perl:
push@A,$_ for reverse q.e...q.n.;for(@A){$_=unpack(q|c|,$_);@a=split//;
shift@a;shift@a if $a[$[]eq$[;$_=join q||,@a};print $_,$/for reverse @A
