Two array-related behaviors that took me off-guard this week.

Zsban Ambrus displayed this technique for ignoring a list assignment.

 >> x, (*), z = [:x, :y, :z]
 => [:x, :y, :z]
 >> x
 => :x
 >> z
 => :z

And Christian Neukirchen showed the spooky split that the array constructor function does.

 >> Array("foo\nbar")
 => ["foo\n", "bar"]
 >> $/ = ' '; Array( "i'm in your house" )
 => ["i'm ", "in ", "your ", "house"]
