If it's not constant, don't make it a constant.

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
=> []

Dan

No lie demonstrated. The Dems held the majority, ran committees and
control what is put together and voted upon.. That is by definition
"controlling all legislation". The fact that Republicans have been
able to stop some of this nonsense via the filibuster doesn't change
what I said.
