Hello World

It seems Code Highlighting of CSDN blog doesn't support Perl, but at the same time Ruby & Python are both listed. Why? I personally have no idea at all.

For those wanna have its Perl code segment shown in colors, you can select PHP as option...at least it's partially colored and looks not bad! 

print <<'EOF'; Hello World, Loooooong Time No See You All....EOFmy $god = 'Lady Gaga';print <<"EOF"; Oh, My $god, CSDN blog does not support highlighting Perl code...EOF

Read PHP page at wikipedia, if you have interest on why PHP works here, lol!
