Trying to access local variables of a block

block_local_variables

class Scraper
  def scrape!(&block)
    instance_eval &block
    
    b = block.binding
    eval("p local_variables", b)
  end
end

s = Scraper.new
s.scrape! do
  variable = "some_value"
end

This doesn't work, but it indicates what I would like to see.
