04:41 PM Ruby Bug #12100: CSV converters fail when using single arg proc

I'm pretty sure this will introduce new bugs.
The meaning of an arity of -1 is "any number of arguments".
In reality you're not passing a proc which takes 1 argument (which would
work w/o your patch), but a proc which takes any numb... recursive-madman (Recursive Madman)

11:47 PM Ruby Bug #11103: Reassignment in if block that is not ran, causes variable to become nil

Ruby is behaving as it should here. Your confusion is between local variables and method calls.
Before that 'if' block `mock_input` resolves to the "mock_input" *method* of your class. The 'if' block then declares a variable with the sa... recursive-madman (Recursive Madman)

Could you provide an example that doesn't work?

11:18 AM Ruby Feature #11049: Enumerable#grep_v (inversed grep)

How about implementing `Regexp#invert` instead?
```ruby
/b/.invert #=> /[^(?:b)]/
```
Like this for example:
```ruby
class Regexp
def invert
self.class.new("[^(?:#{source})]")
end
end

08:40 AM Ruby Feature #11034: Nil Conditional

This is similar to a pattern I have seen somewhere else:
```ruby
var = 123.4
var.try.round #=> 123
var = nil
var.try.round #=> nil
```
Which doesn't introduce a new operator and can be implemented like this:
```ruby

It doesn't actually:
```ruby
2.2.0 :001 > puts %w(a b c).to_s
["a", "b", "c"]
```
`join` joins without a comma:
```ruby
2.2.0 :002 > puts %w(a b c).join
abc
```
Also, I agree with your ... recursive-madman (Recursive Madman)

04:08 PM Ruby Feature #10883: Passing a block to itself

Note that for your example that wouldn't be needed:
```
a = an_array.foo.bar
a[1..a.length-1].baz
```
is equivalent to
```
an_array.foo.bar[1..-1].baz

08:25 PM Ruby Feature #10849: Adding an alphanumeric function to SecureRandom

Suggestion: Rename `graph` to `printable` and possibly add an `:allow_space` option?

06:00 AM Ruby Feature #10683: fix inconsistent behavior of Kernel.Hash()

> I don't think either of your proposed options will be accepted.
I can see that making `Hash(obj)` equivalent to `obj.to_h` would be a major change in functionality.
The primary reasons for opening up this issue are two points:

07:35 PM Ruby Feature #10683 (Open): fix inconsistent behavior of Kernel.Hash()

I find the way the global function `Hash` (aka `Kernel.Hash`) works a bit confusing.
To illustrate:
```ruby
Hash(nil) #=> {} (1)
Hash({}) #=> {} (2)
Hash([]) #=> {} (3)
# but
Hash([[1,2]]) #! TypeError (4)
```
