Maybe I'm just being thick, but wouldn't it just be easier (and much
closer to what you are actually trying to do) to say

["a", "b", "c", "d", "e"].each do |x|
     puts x unless x == "c"
end

I'll admit I'm also new to Ruby but isn't the above the more "rubyish"
way to achieve what you're trying to do?
