# KWattr

Keyword arguments meet attribute definitions and initialize:

```ruby
class FooBar
  kwattr :foo, :bar
end

FooBar.new foo: 42, bar: 21
# => #<FooBar @foo=42, @bar=21>
```

instead of

```ruby
class FooBar
  attr_reader :foo, :bar

  def initialize(foo:, bar:)
    @foo = foo
    @bar = bar
  end
end
```

### Default values

```ruby
class Foo
  kwattr foo: 42
end

Foo.new
# => #<Foo @foo=42>
```

### Overriding initialize

The default initialize is prepended so there's no need to call `super` in
initialize, and attributes are already set.

```ruby
$over = []

class Over
  kwattr foo: 42

  def initialize
    $over << foo
  end
end

Over.new
Over.new foo: 21
$over
# => [42, 21]
```

### Subclass

```ruby
class Bar < Foo
  kwattr :bar
end

Bar.new bar: 42
# => #<Bar @foo=42, @bar=42>
```

### Include

```ruby
module Mod
  kwattr :mod
end

class Inc
  include Mod
end

Inc.new mod: 42
```
