Re: copy by value implementaion of lua strings

[Coda Highland <chighland@...>]

Fortunately, no. Lua strings are immutable and reference-counted.
Short strings get interned into a pool so that they're represented
application-wide by a simple numeric value, and longer strings are
shared instead of copied until they're garbage-collected.
