Subject: [ruby-talk:24165] Re: C-like enum

Here's an improved version based on input from David Alan Black and Nat Pryce:

module Kernel
    # simple (sequential) enumerated values
    def enum(*syms)
        n = block_given? ? yield : 0
        syms.each_with_index { |s,i| const_set(s,i+n) }
    end

    # enumerated values suitable for bitwise OR-ing
    def set(*syms)
        syms.each_with_index { |s,i| const_set(s,2**i) }
    end
end

Thanks,
