print is a language construct and not a function and since the parenthesis are optional its really:

print '' && false

Where the second expression is considered part of the first.

Thanks, and you're right. This behaviour is described in the manual at include's page. But bit confusing, that -- still if it's optional -- I 
put the parenthesis, why would not "use" them?
