I don't think that lua will become the default, as many scripts still
want lua-5.1.x.
the ideal should be to have versioned versions of lua (like lua51,
lua52, lua53, etc.) all parallel-installable together so that whatever
needs one specific version could use it but this is not made easy by
the upstream lua developers.
if you (or whoever else) feel like to submit a new lua52.SlackBuild,
as a dependency of lsyncd, that will be parallel installable with the
lua we have, you are welcome: if you want/need you can also modify the
lua.SlackBuild that we have in our repository (you can even take
maintainership, if you prefer), taken that it will still play fine
with what we have in our repository.
