Joel,
I can show you another "black magic code" from my
http://www.sweb.cz/LMecir/contexts.html
f: func [level] [
make object! [
a: 2 * level
b: either zero? level [
f 1
] [none]
a: a + 1
]
]
probe f 0
make object! [
a: 0
b: unset
]
It can be repaired as follows:
make-object: function [
{
A non-modifying make object version,
returns an object with any self value
}
[throw]
blk [block!] "object spec"
/proto
prototype [object!] "object prototype"
] [result getres] [
getres: func [value] [result: :value]
blk: compose [(:getres) :self (:blk)]
error? make either proto [prototype] [object!] copy/deep blk
result
]
f: func [level] [
make-object [
a: 2 * level
b: either zero? level [
f 1
] [none]
a: a + 1
]
]
probe f 0
make object! [
a: 1
b:
make object! [
a: 3
b: none
]
]
Regards
Ladislav
