But that produces the error "Use of uninitialized value $_ in exponentiation (**) at coderef.pl line 19." The problem is your use of $_. You pass it to the coderef as an argument, but you never set it! And within the coderef -- ie. subroutine -- the first argument passed is aliased to $_[0] as with all subroutines. To be able to use $_ within the coderef, you need to set it before calling the block. Try:
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
