Hi REBOLians:
About object private members, could anybody explain this to me:
<code>
o: context [
_a: 5
set '_b 10
get-a: does [print-a]
set 'print-a does [print _a]
set 'get-b does [print _b]
]
</code>
Let's try:
>> o/get-a
5
>> o/get-b
** Script Error: Invalid path value: get-b
** Near: o/get-b
>> source o
o:
make object! [
_a: 5
get-a: func [][print-a]
]
>> o/_a
== 5
>> o/_b
** Script Error: Invalid path value: _b
** Near: o/_b
>>
So... it looks like within an object, the use of 'set invoque a
privatization of the word, which is not any more visible from the outside.
Great: I can use this property for making private members, but this way of
doing is still strange to me.
Any clue why a 'set-word! has two different ways of handling things, within
this context ?
