In response to Jay's answer to my post, I stripped down my experimental C code
to something presentable — and realized with a shock that by pushing
of the table onto the stack, their order is reversed! So lua_concat
does what it should!
Sorry about the noise.
This does not mean that I accept Jay's point about implicit parentheses — but
Denis has taken that up, allowing me slink away quietly in disgrace.
