## Miscellaneous changes ## Miscellaneous changes
* lib/objspace/trace.rb is added, which is a tool for tracing the object
allocation. Just by requiring this file, tracing is started *immediately*.
Just by `Kernel#p`, you can investigate where an object was created.
Note that just requiring this file brings a large performance overhead.
This is only for debugging purpose. Do not use this in production.
