Count my vote as well, perhaps for Lua 6.0? In Ruby strings are
mutable. Ruby introduces a new type called 'symbol' that are
interned and used for indexing and comparison [1]. I think such a
scheme would resolve a couple of issues (at least for me); for
example I could then use Lua string for mutable binary data buffers
instead of having to create a new user data.
While we are off topic, let me also include my wish for an integer
number type. I hate to maintain special builds of Lua.
