Error in `fintersect` if the first data table contains a column called "y"

[mnazarov]

library(data.table)
dtA <- data.table(y = 1)
dtB <- data.table(y = 2)
fintersect(dtA, dtB)
#> Error in funique(y): is.data.table(x) is not TRUE

The issue is in:

data.table/R/setops.R

Line 70 in 659657a

x[funique(y), nomatch=0L, on=names(x), mult="first"]

I guess the solution could be to substitute funique(y) with something like
funique(get("y", envir = parent.frame(3))).
