Subject: How to get the code block to be executed from a file?

Hi,

When working with  method blocks in ruby, how to get the code block to
be executed from a file? In the below example, I want to read the 2
lines in the block (line1, line2) from a file instead of directly
placing them as mentioned below. The following works fine, but when
passing these to lines (line1, line2) by reading from a file, ".call"
doesn't seem to be successful; no output; It doesn't throw any
exceptions
either.

def method_execution(&method_block)
    begin
      method_block.call
    rescue => msg
        fail("Test Failed : " + msg)
    end
end

def test
  method_execution{
    s =  5 + 4      # line 1
    puts s           # line 2
  }
end

Any suggestions are appreciated. Thank you..
