by explicitly setting `Warning[:deprecated] = true`.
I removed "capture_io" at 79063d8cbf, but
it printed the warning when `RUBYOPT=-w`.
This change makes the warnings enabled explicitly, capture and check the
warning.
Previously, lambdas were converted to procs because of how
rb_block_call works. Switch to rb_funcall_with_block, which
handles procs as procs and lambdas as lambdas.
Fixes [Bug #15613]
Currently, there is not a way to create a sized enumerator in C
with a different set of arguments than provided by Ruby, and
correctly handle keyword arguments. This function allows that.
The need for this is fairly uncommon, but it occurs at least in
Enumerator.produce, which takes arugments from Ruby but calls
rb_enumeratorize_with_size with a different set of arguments.
A Yielder object can now be directly passed to another method as a
block argument.
```ruby
enum = Enumerator.new { |y|
Dir.glob("*.rb") { |file|
File.open(file) { |f| f.each_line(&y) }
}
}
```

They return an Enumerator::Chain object which is a subclass of
Enumerator, which represents a chain of enumerables that works as a
single enumerator.
```ruby
e = (1..3).chain([4, 5])
e.to_a #=> [1, 2, 3, 4, 5]
e = (1..3).each + [4, 5]
e.to_a #=> [1, 2, 3, 4, 5]
```

When each() takes arguments, it is never safe to assume that the iteration
would repeat the same number of times as with each() without any
argument. Actually, there is no way to get the exact number, so the
size should be set to nil to denote that.

This commit introduces new core class Enumerator::ArithmeticSequence.
Enumerator::ArithmeticSequence is a subclass of Enumerator, and
represents a number generator of an arithmetic sequence.
After this commit, Numeric#step and Range#step without blocks
returned an ArithmeticSequence object instead of an Enumerator.
This class introduces the following incompatibilities:
- You can create a zero-step ArithmeticSequence,
and its size is not ArgumentError, but Infinity.
- You can create a negative-step ArithmeticSequence from a range.

FrozenError will be used instead of RuntimeError for exceptions
raised when there is an attempt to modify a frozen object. The
reason for this change is to differentiate exceptions related
to frozen objects from generic exceptions such as those generated
by Kernel#raise without an exception class.
