The -M switch adds a "use Module" statement to your code.

Hi,
I think it is good to have foreach and for loop
even tough they are the same
if you are searching in a file you can almost make a sentence
foreach $line(@infile) #<-- to me this is more readable
than
for $line(@infile)
But for loop, I use it only for numbers
for(1..53) or for( $i=0;$i<50;$i++)

In Perl, 'for' and 'foreach' are the EXACT SAME THING.
for $x (@list) ...
foreach $x
