irb(main):001:0> f=[1,2]
=> [1, 2]
irb(main):002:0> while 1 do
irb(main):003:1* f.each do |i|
irb(main):004:1* end
SyntaxError: compile error
(irb):004: syntax error
        from (irb):004

It seems like irb is trying to close the while with that first end
instead of the f.each.  Same thing happens with syntax coloring in vim.
