[REBOL] Re: On mutability and sameness

From: kenneth:nwinet at: 17-Jun-2001 17:46

Joel, I'm being dense again. When you say the integers are immutable in Rebol (implying they may be mutable in other languages?); I'm seeing a distinction without a difference. You referred to mutating verses replacing.
> a: 42 > a: a + 1 ;=43
Could I not see this as an example of mutating the rightmost bit? ...or perhaps... Are you saying a new symbol 'a' is created in a table so that the place where 42 is stored is unrelated to the place where 43 is stored? ...or... The truth is out there (but unlike the x-files I'm about to be enlightened! ;-))
