[REBOL] Re: Rebol pickling recipes ?

Hi Laurent,
> What exactly do you mean by "loading" words without using 'load ?
As I see it, Gabriele meant, that you can make a word without using LOAD as follows: a-word: first make block! "xxxyyy" probe a-word ; xxxyyy The word we made this way cannot be found in REBOL/WORDS: in rebol/words a-word ; == none

Not exactly. Let's see this: block1: reduce [a-word] ; == [xxxyyy] block2: compose/deep [[(a-word)]] ; == [[xxxyyy]] block3: reduce [first use block1 block2 first use block1 block2] set first block3 1 set second block3 2 Now we can explore the properties of BLOCK3: probe block3 ; == [xxxyyy xxxyyy] reduce block3 ; == [1 2] Let's suppose, that we just use the MOLD function to make BLOCK3 persistent. If we LOAD the result back, we don't get a block having the same properties as BLOCK3 and that is the trouble. Regards -Ladislav
