Which version of the survey package you have in mind? I took a look at
the latest version available on CRAN (3.37 at the time of this post,
[*]) and the R/surveyby.R file has somewhat different code on lines 57
and 74.

In particular, attr(*, "var") is assigned much later, from variable
named covmat.mat, which is also computed later than line 74.
