I'm trying to check whether the given key exists in the hash.
The simple example:
use feature ':5.10';
my %a = (a = 1, b = 2);
say %a ~~ 'a' ? 'YES' : 'NO';# says NO -- why?
say %a ~~ 'c' ? 'YES' : 'NO';# says NO
say 'a' ~~ %a ? 'YES' : 'NO';# says YES
say 'c' ~~ %a ? 'YES' : 'NO';

but why don't you just call exists on the hash key? there is no win to
using smart matching for that. it is included for consistancy but it
isn't needed for hash keys.
I just want to understand how does it work :)

Hallo all!
I beg your pardon for this question - the question more theoretical,
rather than practical.
Whether there is a modules for geometry transformation of the images?
In particular, I need rotate and change geometry (perspective, resize)?
Thanks a lot for any answers!

Yes.
ImageMagick is the most common way to do this. It's a toolkit
and how can I get rid of it:
Content-type: text/html
Content-transfer-encoding: binary
Content-disposition: inline
Content-length: 155
Thanks,
Mark

Hi
Wim has already presented the solution for your problem;

I do this:
$#array = $N+100;
print_array($array[$N]);
this should be
print $array-[$N]
I see, but $array here
be very big and I wish to avoid
excessive copying of data. Therefore I don't want use splice function.

Equivalent VFS_VGET(9) for example?

That's right, but you should better use
my $viRetValue = system(command, string);
In this case the command interpreter will not be used and that is more safe.

Hallo!
Try to change directory to $ARGV[0] before open:
chdir($ARGV[0]) || die Cannot change dir: $!\n;
opendir $DIRHANDLE, ./;
.
And (may be) It is better to use lstat(2) instead of stat(2) ?
In this case there will be correct dates of symbolic links.

The page is displayed correctly.
But why is the query string added? The form's default method should be post,
and the username/password are not displayed in the query string.

Sure (abbreviated):
