I noticed that the Lua arithmetic operators in 5.4 will not coerce
strings to numbers ... is my understanding correct? I think this is
good for performance as it avoids a function call for converting
values but presumably this is a breaking change for existing code that
may be relying on this feature?

See previous discussions around LUA_NOCVTS2N
e.g. http://lua-users.org/lists/lua-l/2015-01/msg00623.html


Also noticed that var args will now be put into a table - wanted to
check if this is just an implementation detail - i.e. no user visible
impact on either Lua or the C API?

_ARG is user-visible.



Ooh select()-free vararg indexing, this will be interesting!

I guess ... is just a glorified (read: faster) table.unpack?
