Well, it's just a discussion that went off on a tangent from 
benchmark results; there is no right or wrong. :-) I look at them 
as microbenchmarks anyway.

If we follow the example of the boost's assign library, then 
chain()()() can be a valid pattern in Lua, if one chooses to use 
such a pattern, e.g. chain(123)()()("foo")("bar").

Trying to gauge the popularity of this pattern, I tried searching 
for boost's "ptr_insert(" and turned up zero examples... so, 
/caveat emptor/ then. I'll say no more. :-)
