Hi, I would like to add some debugs for my simple ruby functions and I wrote a function as below,

def debug(&block)
  varname = block.call.to_s
  puts "#{varname} = #{eval(varname,block)}"
end

debug {:x} #prints x = 5
debug {:y} #prints y = 5

I understand that eval is evil. So I have two questions.

1. Is there any way to write that debug method without using eval? If NO is there a preferred way to do this?
2. Is there any way to pass a list of arguments to this method? I would ideally prefer debug {:x, :y. :anynumOfvariables}. I could not quite figure out how to factor that into the debug method (i.e, to take a list of arguments)
