scala> print "Hello"
<console>:1: error: ';' expected but string literal found.
       print "Hello"

This is supposed to print "Hello"

It does work if you ask nicely:

scala> object please {
     |   val print = Predef.print _
     | }
defined module please

scala> please print "Hello"
Hello

This isnt the answer to the question. You just made it work by adding additional scaffolding code – Aravind Yarram Jun 23 '14 at 16:56
Why not just `Predef print "hello"` directly instead of declaring `please`? Anyway, it's probably better just to use the parentheses. – DaoWen Jun 23 '14 at 17:13

@DaoWen He's definitely trolling, but I laughed anyway. – wilkystyle Oct 10 '14 at 02:23

Use the right syntax:

scala> print("Hello")
Hello

@Pangea it depends. [Sometimes, you can drop parenthesis, sometimes, you're not](http://stackoverflow.com/q/1181533/298389) – om-nom-nom Jun 23 '14 at 15:15
