Subject: [ruby-core:64844] [ruby-trunk - Feature #10215] [Open] prohibit subclassing for classes without allocator in Ruby

Issue #10215 has been reported by Hans Mackowiak.

----------------------------------------
Feature #10215: prohibit subclassing for classes without allocator in Ruby
https://bugs.ruby-lang.org/issues/10215

* Author: Hans Mackowiak
* Status: Open
* Priority: Low
* Assignee: 
* Category: 
* Target version: 
----------------------------------------
for the Ruby side it might be interesting if there is a way to prohibit the subclassing of classes that has no allocator like Symbol or Integer or TrueClass

but blocking it generally would break some C-Ext where it has base classes with undefined alloc
