Arch Linux

Description:
The package hasn't been updated for Lua 5.4.
I don't know if Lua 5.4 is supported upstream, since it seemingly hasn't been updated in 11 years. From my testing it doesn't even seem to work for Lua 5.3, as that produces the same error as my improvised package that simply installs into `/usr/share/lua/5.4`.

I believe it to be the reason for moonscript being broken on Lua 5.4, but I'm not entirely sure since I never dealt much with the Lua ecosystem.

Steps to reproduce:

```
$ pacman -F /usr/share/lua/5.3/alt_getopt.lua
usr/share/lua/5.3/alt_getopt.lua is owned by community/lua-alt-getopt 0.7.0-8
usr/share/lua/5.3/alt_getopt.lua is owned by community/lua53-alt-getopt 0.7.0-9
