----------------------------------------
Bug #8438: Kernel.eval can not Reliably Create new Variables
https://bugs.ruby-lang.org/issues/8438#change-39509

Author: martin_vahi (Martin Vahi)
Status: Rejected
Priority: Normal
Assignee: 
Category: core
Target version: 
ruby -v: ruby 2.0.0p195 (2013-05-14) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


Variables that are created by the Kernel.eval are deleted from the execution context before the method eval exits, despite the fact that the execution context that is fed to the Kernel.eval by a Binding instance is still in use.

That seriously hinders the use of reflection.

Demo resides in the attached flaw_demo.rb.
