We are also considering the following changes:
- string.pack/string.unpack (along the lines of struct/lpack)
- Mike Pall's implementation for yield (using longjmp), allowing yields
in several places not allowed currently (inside pcall, metamethods, etc.)
- some form of bit operations. (We are not very happy with any
known implementation. Maybe just incorporate bitlib?)
- there is already a new function luaL_tolstring (along the lines of
the 'tostring' function). Maybe we should define a lua_rawtostring (no
coercions from numbers) and then use luaL_tolstring ("full" coercion
from other types) when we want to allow coercions. The point is where
to use one and where to use the other. (The current lua_tostring behavior
would be deprecated in the future...)
