This works as expected:
"[.foo" <- function(x, i, j) {
sx <- substitute(x)

}
x <- 1:10
class(x) <- "foo"
x[y == z, a(x)]
#> [1] 132

Dear Terry,
You misunderstand the note. The problem is that your tar.gz is too
large. The critical bit is:

The CRAN repository policies state:
"Packages should be of the minimum necessary size. Reasonable
compression should be used for data (not just .rda files) and
When I run R CMD check on the survival package I invariably get a note:

single bracket subsetting can accept an unquoted expression to be evaluated in
the context of my object.
A simple example from the data.table package looks like this:
DT <- data.table(col1 = c('a', 'b',
