This is a work version. All details may change in the final version.

Here are the main changes since the previous work version:
- new _ENV proposal
- generational collector (very experimental)
- light C functions
- order tag methods follow the same rules of other binary operators
- lua_absindex
- \0 in patterns
- empty statement
- options in io.lines

The manual has been updated and most glitches reported in work2 have been fixed.
The complete diffs are available at
	http://www.lua.org/work/diffs-lua-5.2.0-work2-work3.txt

(This is a very large diff because the manual has been rearranged.)

All work versions are available at

All feedback welcome. Thanks.
