06:59 PM Ruby Bug #10450: multiple assignment in conditional

Ok, yes...but if your intention with this feature request is simply to treat the multiple-assignment statement as a whole as the test condition, you can already do that like so:
~~~
if _ = (a, b = *multi_ret_val_meth)
puts "Multi-... jballanc (Joshua Ballanco)

10:11 AM Ruby Bug #10450: multiple assignment in conditional

Yes, but consider:
~~~
if a = (b, c = false, false)
puts "a is #{a}, b is #{b}, c is #{c} and everything together is true"
end
~~~
So if you were hoping to use multiple assignment to check the `&&`-ed boolean values of the in... jballanc (Joshua Ballanco)

08:56 AM Ruby Bug #10450: multiple assignment in conditional

Which of the multiple values assigned would you have used as the test for the conditional?
~~~
if (a, b = true, false)
puts "Should this run?"
else
puts "Or this?"
end
~~~ jballanc (Joshua Ballanco)

Would be nice if we could get this in 2.2 (if someone could update the target version, I'd appreciate it). jballanc (Joshua Ballanco)

05:55 PM Ruby Feature #9453 (Rejected): Return symbols of defined methods for `attr` and friends

With Ruby 2.1 returning a symbol from `def` and `define_method`, that leaves `attr`, `attr_reader`, `attr_writer`, and `attr_accessor` as ways to define methods that still return nil. This is unfortunate, because it prevents the use of m... jballanc (Joshua Ballanco)

08:52 PM Ruby Misc #9438: Implementation naming

As a point of comparison, I've often heard members of the Python community refer to the original implementation as "CPython". Also, not that this should necessarily carry any weight, but it's worth noting that CPython has its own page on... jballanc (Joshua Ballanco)

05:34 PM Ruby Feature #8839: Class and module should return the class or module that was opened

Just to throw my 2¢ in...

04:59 AM Ruby Feature #8661: Add option to print backtrace in reverse order (stack frames first and error last)

You can already accomplish something like this yourself:
```ruby
begin
raise "Hello!"
rescue Exception => e
puts e.backtrace.reverse.join("\n")
puts e.message
end
```
Simple!
