Subject: Re: interested in metaprogramming?

what about using define_method from ruby1.8.4 ? it also accepts a
block as argument..
alternatively it will look nicer to use the eval %{ .... } notation
than the HEREDOC.

if you use heredoc you coud do it this way, to convey the meaning that
the sting represents code:

  eval <<-CODE
                sdjifklsdnkdfksd
                dl�sdkl�l�fsd�s
             CODE
