Subject: [Kochi-pm] caller - a perl subroutine which we normally wont make
	note of.
Message-ID: <4AF25084.20809@gmail.com>

Hi all,

I am trying to introduce you to a Perl function '*caller*' which most of 
us didn't pay attention to. I do remember I used it long back, but never 
used for last 4 years.

caller is a perl built-in function. It returns the context of function 
call in any subroutine.

Syntax:

( $package, $filename, $line, $subroutine, $hasargs, 
  $wantarray, $evaltext, $is_require, $hints, $bitmask, $hinthash ) = caller(1);

The only expression it takes is an integer. Value 1 means, returns the 
details of the function called current function.

For more details, you may read http://perldoc.perl.org/functions/caller.html


May be at some point you may need it :)

Thanks and Regards
Varghese Chacko

How Smart Is Your Right Foot?
==============================

Just try this. It is from an orthopedic surgeon. This will
boggle your mind and you will keep trying over and over again
to see if you can outsmart your right foot - but you can't.

It's preprogrammed in your brain!

1. WITHOUT anyone watching you - they will think you are GOOFY,
and while sitting where you are at your desk in front of your
computer, lift your right foot off the floor and make clockwise
circles with it.

2. Now, while doing this, draw the number six in the air with
your right hand. Your foot will change direction.


I told you so! And there's nothing you can do about it!

You and I both know how stupid it is, but before the day is
done, you are going to try it again, if haven't already done so.

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I--
I took the one less traveled by,
And that has made all the difference
