This looks very interesting! Would someone be willing to translate to english? I've only got a vague idea of what is being discussed.

To try and cut to the core of the issue: in Ruby 1.8 it was common practice to use the String class to represent both "proper strings" as well as a "bag-o-bytes". In Ruby 1.9, you can only properly use the String class to represent "proper strings". For a "bag-o-bytes" we're left with Array, but there are times when Array is not the right abstraction (e.g. reading data from a socket, identifying a start and stop token, and writing the bytes between to a file on disk). Also, the "BINARY" encoding is not the right abstraction, because you still have an object which will worry about encodings and, due to Ruby always trying to do "the right thing", bugs can be very difficult to track down. Consider:

[ruby-core:39881] [Ruby 1.9 - Feature #5392][Open] Symbol GC

From: Kurt Stephens <ks.ruby@...>
Date: 2011-10-03 16:41:14 UTC
List: ruby-core #39881
Issue #5392 has been reported by Kurt  Stephens.

----------------------------------------
Feature #5392: Symbol GC
http://redmine.ruby-lang.org/issues/5392

Author: Kurt  Stephens
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 


I looked more into Symbol GC.  The biggest problem is IDs are not VALUEs.  My outburst at RubyConf based on my stupid assumption that they were -- I was trying to attack the problem using WeakRefs.

If IDs were VALUEs and Symbols were allocated like any other Object, the existing GC mark and root machinery (including C stack root scans), would take care of it, with an additional sweep of the global_symbol lookup tables.

However, the remaining issue is IDs stored in globals.  No matter what, IDs stored in C globals will need to be rb_gc_register_address(VALUE*) roots -- this means CRuby API/contract changes.

Adding a standalone ID mark table and a rb_gc_mark_id() function will not fix problem of lone IDs on the C stack.

What was the original reason to distinguish Symbol IDs from Object VALUEs, besides making lexer tokens simple to map.
Would changing IDs to be allocated VALUE objects simplify internals anyway?  This change could also allow Anonymous Symbols and Anonymous Methods.
