[ruby-core:114968] [Ruby master Feature#19884] Make Safe Navigation Operator work on classes

Issue #19884 has been updated by p8 (Petrik de Heus).


There's multiple examples in the Rails code base:
https://github.com/rails/rails/blob/7f7f9df8641e35a076fe26bd097f6a1b22cb4e2d/railties/lib/rails/generators/named_base.rb#L139
https://github.com/rails/rails/blob/7f7f9df8641e35a076fe26bd097f6a1b22cb4e2d/railties/lib/rails/generators/generated_attribute.rb#L67C1-L76

```ruby
def valid_type?(type)
  DEFAULT_TYPES.include?(type.to_s) ||
    !defined?(ActiveRecord::Base) ||
    ActiveRecord::Base.connection.valid_type?(type)
end
```

It would be nice to rewrite this as:
```ruby
def valid_type?(type)
  DEFAULT_TYPES.include?(type.to_s) ||
    ActiveRecord&::Base&.connection.valid_type?(type)
end
```

Feature #19884: Make Safe Navigation Operator work on classes
https://bugs.ruby-lang.org/issues/19884#change-104840

* Author: p8 (Petrik de Heus)
* Status: Open
* Priority: Normal
----------------------------------------
If a class might not be defined we need to add a conditional:

```ruby
defined?(ActiveRecord::Base) && ActiveRecord::Base.some_method

```

It would be nice if we could use the Safe Navigation Operator instead.

```ruby
ActiveRecord::Base&.some_method

```
