Currently I'm doing this:

query string. AND can I just say... Yuck!
Anyway, my solution seems kludgy and I don't like it. It smells funny.
CGI.pm docs mention a class method restore_parameters() that works
like so:
open (IN,"test.in") || die;
restore_parameters(IN);
close IN;
...but there's no other mention of it, and no mention of an object
method. I can't stand using the functional interface for CGI.pm.
Isn't there any way to just reset an existing CGI object directly
without calling the constructor all over again?

Actually, even that's not working right. Dammit.
According to the docs, I can create a new CGI object with a properly
formatted query string as an argument and *those* params are supposed
to be what it parses.
Quoth the docs:
"or from a properly formatted, URL-escaped query string:
$query = new CGI('dinosaur=barney&color=purple');"
But if I try this, and even if I am VERY careful to make sure it's in
scalar context:
use CGI();
my $cjax = new CGI;
my $POSTDATA = $cjax->param('POSTDATA');
undef $cjax;
my $cgi = new CGI($POSTDATA);
I still get back:
print join ', ', $cgi->param();
prints:
POSTDATA
So WTF??
BTW -- yes, POSTDATA taken as a param does contain a properly
formatted string, like so:
POSTDATA: pixel=43:62:yellow:8&pixel=43:65:yellow:8&pixel=43:76:yellow:
8&pixel=43:84:yellow:8&pixel=45:94:yellow:8&pixel=45:98:yellow:
8&pixel=45:102:yellow:8...etc...
So the string is right. I should definitely not need to write this to
a file, and honestly if the docs are being wrong about this part, I
don't expect them to br right about reading from a file, either.
