Good list.

My personal there's-got-to-be-a-better-way list for Lua
is pretty short nowadays (thanks to Lua 5.1):
- Yield from everywhere.
I'm starting to think that yield is hiding an ambiguity. The fact that
you cannot use yield to both implement control-inversion and
thread-scheduling independently makes me wonder if there isn't some
better way.
- Explicit finalization.
Agreed.
- Standardized module installation.
Agreed.
- Userdata type checks.
I think this can be accomplished easily now that userdata have both
"class" and "instance" tables, although I think the mechanism could be
improved slightly.
- Better Lua/C API (something for 6.x).
It would have to be even simpler than the current one, which is a
challenge.
And a few minor issues with out-of-the-box behaviour:
- Hex numbers (parser + luaO_str2d with strtol fallback for non-C99)
Agreed.
- Missing bit operations (math.*)
I'd put bit operations in string.*, not math.*. We can argue about this
after 5.1 comes out.
- xpcall()
- package.cpath (as of 51w6)
- Makefile (OS detection, -ldl or not, creating module dirs etc.)
- lua_Number (support for types other than double)
Agreed with all the above.
