Subject: Regexp#options (RCR #43)

Hi all,

As I was going through the accepted RCR's, came across
#43, which was accepted.  This added the 'options()'
method for Regexp objects.

Testing this with 1.8 (2003-06-28) I immediately
noticed two things.  First, flags to Regexp are
ignored, which I didn't know.  Second, I'm confused as
to what is supposed to be returned.

# example using longhand
irb(main):001:0> r =
Regexp.new(/\w+/,Regexp::EXTENDED)
(irb):1: warning: flags ignored
=> /\w+/

# example using shorthand
irb(main):002:0> r.options
=> 0irb(main):003:0> r = /\w+/xi
=> /\w+/ix
irb(main):004:0> r.options
=> 3

My guess is that it's returning length + 1, instead of
the options themselves.  If my opinion carries any
weight, I would like r.options (using the last
example) to return ["x","i"].

Is this a bug?

Regards,

Dan
