For those new to the project: this is the file system that's used alongside Doppio, written by the same John Vilk. Both projects are excellent examples of large Typescript projects, the code is very well documented and readable.
In seriousness, is the performance of Doppio bearable? Also, what are the use cases for a thing like that?
http://www.codemoo.com/ uses it to teach students basic Java in a game format.
Still this is insanely cool.
