    use warnings; would have caught that:

    C:\test>perl -wE"if( -d abc ) { say 'hi' }"

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
