They can’t be entirely free, can they? Doesn’t the structure have to be persisted on disk somewhere?

In code golf competition the shortest program (in bytes) wins.
I don't think anyone ever included there the bytes taken by the metadata of the files, so in theory any solution implemented in this language is the best possible: 0 bytes.
Although it it did not count against my quota, it certainly was not free :)
Or am i missing that this is a joke?
That seems like the brainfuck equivalent of this idea. I was thinking that you'd create a tree of folders to represent the abstract syntax tree of the program, with folder names being the actual syntactic elements/atoms of the program.
