Issue #15842 has been reported by jeremyevans0 (Jeremy Evans).
----------------------------------------
Feature #15842: Allow DelegateClass() to module_eval given block
https://bugs.ruby-lang.org/issues/15842
* Author: jeremyevans0 (Jeremy Evans)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
----------------------------------------
Methods that return classes often module_eval the given block
(e.g. `Class.new` and `Struct.new`). This allows `DelegateClass` to
work similarly. This makes it easier to use `DelegateClass`
directly without subclassing, so as not to create an unnecessary
intermediate class. Example:
```ruby
MyClass = DelegateClass(ClassToDelegateTo) do
def initialize
super(obj_of_ClassToDelegateTo)
end
end
```
Attached is a patch that implements this proposal.

Issue #15842 has been updated by jeremyevans0 (Jeremy Evans).
As delegate.rb is unmaintained, unless someone objects in the next week, I plan on committing this feature.
