Subject: Re: Truncate an arrayI'd thought about that too. This is bad for two reasons.
1. SOME_ARRAY is 'supposedly' a constant, in that ruby
complains if you assign to it more than once.
If it's not constant, don't make it a constant.
2. We didn't really truncate the array, just made a new empty one.

Ok, use Array#clear then:
irb(main):014:0> a = [1,2,3]
=> [1, 2, 3]
irb(main):015:0> b = a
=> [1, 2, 3]
irb(main):016:0> a.clear
=>
irb(main):017:0> a
=>
irb(main):018:0> b
=>
