[REBOL] Re: [Truth test fails]
Hi Tim,
| What would be the use for that feature?
|
It's usefull e.g. when you MOLD or SAVE what you want to LOAD easily:
>> mold none
== "none"
>> mold/all none
== "#[none]"
>> type? load mold none
== word!
>> type? load mold/all none
== none!
>> save/all %/c/test.r none
>> load %/c/test.r
== none
>> type? load %/c/test.r
== none!
The same feature applies for objects, too:
>> mold/all context [a: 5]
== {
#[object! [
a: 5
]]}
>> type? load mold context [a: 5]
== block!
>> type? load mold/all context [a: 5]
== object!
HTH,
Christian
