I usually use a quick and dirty hack to avoid regexps (though they're nice.
:-)

 def is_integer(to_test)
    begin
      Integer(to_test)
      return true
    rescue ArgumentError
      return false
    end
  end

Basically, I think whoever wrote the Integer-class is smarter than me, so
why not let them figure it out?
It's probably an abuse of exceptions, but it works just fine.
