With Lua, it becomes near impossible for a program like lux to edit the manifest.

For example, how would I `lx add <dependency@version>` if the `dependencies` table might be generated by a Lua function?

Lux defaults to TOML, but if you really want Lua, it also supports an `extra.rockspec` in the project root, which shares the same format as the luarocks RockSpec format.

The function would be "compile time" so that function would be evaluated when you call `lx add <dependency@version>`, I'd also assume that the previous configuration would be cached and a diff shown of dependencies.

But I would also accept that it would be a subset of Lua that could define tables, but not contain functions. The data only declarative sublanguage.

We want to be able to write updated dependency specs to the manifest.
