This illustrates the issue

> x = 1:5; .Internal(inspect(x)) 
@92fcbc8 13 INTSXP g0c3 [NAM(1)] (len=5, tl=0) 1,2,3,4,5
> address(x); .Internal(inspect(x))
[1] "0x92fcbc8"
@92fcbc8 13 INTSXP g0c3 [NAM(2)] (len=5, tl=0) 1,2,3,4,5

and a confusion caused by it, where x is replaced rather than updated

> x = 1:5; .Internal(inspect(x)); x[] = cumsum(x); .Internal(inspect(x))
@9684540 13 INTSXP g0c3 [NAM(1)] (len=5, tl=0) 1,2,3,4,5
@9684540 13 INTSXP g0c3 [NAM(1)] (len=5, tl=0) 1,3,6,10,15
> x = 1:5; address(x); x[] = cumsum(x); address(x)
[1] "0x9ebed00"
