use Modern::Perl;

{
    local $/ = '';
    say +(split /\n/)[0] while <DATA>;
}

__DATA__
ram: 702
Func: Func_file_permission
testing

tam: 768
Func: Func_file_permission
test

cham: 803

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
