[REBOL] Re: On mutability and sameness

From: lmecir:mbox:vol:cz at: 17-Jun-2001 3:47

Hi, a sample thought (you need not take it seriously):
> MY MODEL: > > a) All set-path expressions cause something to be mutated. > The "something" is identified by the set-path up to the > last #"/" and which part of that "something" is identified by > what follows the last #"/". Any such "something" is mutable.
A possible POV: once upon a time the time values in Rebol behaved like: a: 12:30 ; == 12:30 a/hour: 13 ; == 13:30 a ; == 12:30 Back then your rule was incorrect. Your rule hasn't changed since then and therefore it is still incorrect.
