Wow, that's one crazy looking interface! Why bother with encode(t/s), write(file, t) or read(file) when you can use __call, __index and __newindex!

It reminds me of the gyrations I went through when I discovered all the amusing ways to use C++ operator overloading. Lots of fun! Heck, in C++ some of it became part of std::.

Other than the obvious fun, though, is there a benefit I've missed to having the implementation use __call, __index, and __newindex? The indexing doesn't make me think "writing/reading a file". Why not just use two named functions for the API? Brevity? Couldn't that also be achieved with local tread =

Just curious.
