i'm trying to update a file reading logic in modules. But it is not giving the expected results.

with the below code, file reading is not happening inside the main file. Could you pls advise on this? Also you can suggest best practise of reading the files(passed as either arg or as an input through STDIN) inside a module without making any changes in main file

fileread.pl:

use file_read;
my $a=0;
while(<STDIN>){
$a+=1;
}
print "$a";

[download]

file_read.pm:

package file_read;
while(<STDIN>){
print;
}
1;

[download]
perl fileread.pl </tmp/file

[download]

Output : contents of the /tmp/file and $a value is printed as 0 but not 1
