Because the by having your static xml-tags block in the
function it has the effect of doing:
xml-tags: head xml-tags
for each function call.
Otherwise the function leaves the object's xml-tags pegged
at the tail:
. . .
> for x 1 (length? xml-tags) 1 [
. . .
> xml-tags: next xml-tags
Here's the basic effect:
o1: make object! [
f: does [
b: [1 2 3]
print mold b
forall b []
]
]
o2: make object! [
b: [1 2 3]
f: does [
print mold b
forall b []
]
]
>> o1/f
[1 2 3]
>> o1/f
[1 2 3]
>> o2/f
[1 2 3]
>> o2/f
