I don't see why it should take more memory. After having loaded into
Lua, you can of course deallocate the buffer.
And it is even not necessary to uncompress the whole file in one
phase. You can do it a small buffer at a time, and use lua_load.
Of course, I am not saying this is the optimal solution if your
embedded code has tons of megabytes.
PS: I forget to mention that my build tool removes the comments before
compressing the sources.
