10:22 AM Ruby Bug #7975 (Rejected): Why __dir__, not __DIR__

There's a __FILE__ in Ruby 1.x, no __file__
Why __dir__ in Ruby 2.0 is downcase?
It's not consistent. yimutang (Joey Zhou)

11:05 PM Ruby Bug #6500 (Rejected): File#open with a ':binmode => true' opt

Here's the problem, under Windows:
irb(main):001:0> f = File.open('x',binmode:true)
ArgumentError: both textmode and binmode specified

09:28 PM Ruby Bug #6489 (Rejected): A File instance changes its class to IO

I don't know whether it is a bug, or a feature.
1.9.3p194 :001 > f = open('xxx','w')
=> #<File:xxx>
1.9.3p194 :002 > f.class
=> File
1.9.3p194 :003 > f.__id__

10:11 PM Ruby Feature #6261 (Rejected): Enumerable#emap and Enumerable#egrep

I was inspired by Ruby 1.9.x`s Enumerable#chunk and #slice_before, which both take a block and return an enumerator. I wish to introduce two new method into the Enumerable core, which can be implemented in Ruby like this:

12:15 PM Ruby Bug #6202 (Rejected): The 'rescue' modifier can not be used in 'require'

My Ruby version is: ruby 1.9.3p125 (2012-02-16) [i386-mingw32]
I found that the 'rescue' modifier can not be used in 'require', for example:
require 'not_exist' rescue require 'set' # this will raise a LoadError
I must write a... yimutang (Joey Zhou)

02:32 PM Ruby Feature #5798 (Rejected): Range#include? needs some optimization

For example:
('aa'..'az').include? 123
it seems that the procedure is:
1. check whether 'aa' == 123 # false
2. 'aa'.succ # 'ab'
3. check whether 'ab' == 123 # false
4. 'ab'.succ # 'ac'
5. check whether 'ac' == 123 # false

You reminds me! Yes, what I want can be done in this tricky way. Thank you!
However, I think relying on these special global variables ... yimutang (Joey Zhou)

06:03 PM Ruby Feature #5749 (Assigned): new method String#match_all needed

The String class should contain an instance method 'match_all', which is a mixture of 'match' and 'scan'.
The method 'scan' is not a very powerful tool, its result(the yielding thing) is just a matched string or an array of captured s... yimutang (Joey Zhou)

07:58 PM Ruby Feature #5400: Remove flip-flops in 2.0

Magnus Holm wrote:
> Nobody knows them. Nobody uses them. Let's just get rid of flip-flops, shall we?
Well, the flip-flop behavior is useful, so it should not be removed.
However, I agree that the syntax is a bit confusing.
