Readability will depend more on pretty printing than format. Lua data,
JSON, YAML and LPC object code (MUD language) aren't terribly
different to casual inspection. If someone is hand editing values in
any of these, they'll probably just be searching for a key or value
and modifying the value. Pretty printing will help users with grep or
various search and replace operations and the syntax will remain
irrelevant unless they get too zealous with the delete key.

The word "performance" is so nebulous that I didn't bother
differentiating between CPU and memory utilization.
The difference between [[mystate = dofile("objectfile")]] and
[[mystate = decode("objectfile")]] for any arbitrary serialization
format is highly variable depending on the parsing algorithm of the
decode function... and subject to more discussion for less cause here
than it is in communities for languages like Python that have a higher
interpreter overhead. If there's a high load, the environment presents
significant constraints or the parser is particularly inefficient then
there may be a noticeable difference in user space, otherwise it's
self-gratification for the coder. Nothing wrong with that in my
opinion, but IANAP*. ;)
