# two lists
x <- list(a = 1, b = "foo", c = 3)
y <- list(b = 2, d = 4)
x %<-% y
y %<-% x

# one list and one vector
x <- c(foo = 1, bar = 2)
y <- list(foo = "foo")
x %<-% y
y %<-% x

# two vectors
x <- c(a = 1, b = "foo", c = 3)
y <- c(b = 2, d = 4)
x %<-% y
y %<-% x

# duplicated names in x
x <- list(a = 1, b = "foo", b = 3)
y <- list(b = 2, d = 4)
x %<-% y
y %<-% x # be careful, since "3" will cover on "foo" in x, then on "2" in y
