Re: optimisation question

[Roberto Ierusalimschy <roberto@...>]

Yet another small optimization is to remove `ctor' from inside
`numeric_range_tranformer1'. That avoids creating a new closure every
time you call numeric_range_tranformer1.

Also, if you use `..', you do not need to call `tostring':

                        s = s .. "," .. i

That extra function call also costs you some cents...
