Hi,
As far as I know qw(some list item) will import from Carp module only
subs that you've explicitly requested. In this example `some, list,
item` will be available in your namespace but not other from Carp module.
`use Carp;` will import all of them.

I have seen perl syntax like use Carp qw(some list items)so when do we need to
write like this and why is not the items of the module getting imported

I have a feeling this is not a "beginners" question (I've been hacking

You don't want qw{} here. Just do it the brute-force way:

The split did the trick, and cut out a few lines of code

Here is the documentation on it.
( http://www.perldoc.com/perl5.6/pod/perlop.html#qw%2fSTRING%2f )
qw/STRING/
Evaluates to a list of the words extracted out of STRING, using embedded
whitespace as the word delimiters. It can be understood as being roughly
equivalent to:
split('
It's a shortcut for assigning words to an array. That statement would return
an array that looks roughly like this:
('"stuff",', '"more stuff",', '"even more stuff"') # Note the double quotes.
Something like ("stuff",&q
