Issue #19163 has been reported by matz (Yukihiro Matsumoto).
----------------------------------------
Feature #19163: Data object should be frozen
https://bugs.ruby-lang.org/issues/19163
* Author: matz (Yukihiro Matsumoto)
* Status: Open
* Priority: Normal
----------------------------------------
If we call `initialize` (via `send`), we can rewrite an existing Data object.
```ruby
d=Data.define(:a, :b).new(1,2)
p d #=> #<data a=1, b=2>
d.send(:initialize, {a:3,b:4})
p d #=> #<data a=3, b=4>
```
Should we freeze the Data object after calling `initialize` for the first time?
Matz.
