fs.copyDirectory

[metabench]

I suggested this in node.js, but the response was that it's not going in because it's a convenience function, and platforms lack the API to do this in one go. Does ayo.js value convenience here?

I also recommend an alias of copyFolder.

I'm inclined to echo the sentiments of nodejs here. Ideally core/stdlib or whatever one calls the available functions that ship with ayojs should be as minimal as possible and ideally provide only either what cannot reasonabley be done in userland, or what would provide a substantial building block to allow interoperation between userland modules. Unfortunately I don't think a function like fs.copyFolderwould fit the description.

In general more the things that can happen in userland the better is it for the ecosystem as change and experimenation can happen much faster there.
