this is hardly "new new". I think, that you need to know how ALL works.
Here is what is the meaning of all [parent object? new new]:
1) it checks PARENT. 2) If true, it checks, whether NEW is and object.
3) If true, it yields NEW as result.
A more understandable way of doing it might be:
new-face: make case [
all [parent object? new] [new]
all [parent word? new] [get-style new]
true [vid-face]
]
