Subject: the value in ensure block is not returned

Here is the sample code:

irb(main):001:0> def test
irb(main):002:1> begin
irb(main):003:2* a = 1
irb(main):004:2> b = 2
irb(main):005:2> b
irb(main):006:2> ensure
irb(main):007:2* a
irb(main):008:2> end
irb(main):009:1> end
=> nil
irb(main):010:0> test
=> 2

I am expecting that 1 should be returned by is 2.

I also write another code to verify:

irb(main):011:0> def test
irb(main):012:1> begin
irb(main):013:2* a = 1
irb(main):014:2> b = 2
irb(main):015:2> b
irb(main):016:2> ensure
irb(main):017:2* a
irb(main):018:2> puts "hello"
irb(main):019:2> end
irb(main):020:1> end
=> nil
irb(main):022:0> test
hello
=> 2

So it is obviously that all codes in ensure block have been run. But the
return value is always the last value before ensure block.
