At this point we can't mix native types, for example it is not possible
|
||||
to make a callable `Array` object...
|
||||
|
||||
For example this will produce a broken instance:
|
||||
This is not possible in current _JavaScript_ implementations directly
|
||||
as most builtin objects rely on "hidden" mechanics and there is no way
|
||||
to combine or inherit them.
|
||||
|
||||
To illustrate:
|
||||
```javascript
|
||||
var CallablaArray = object.Constructor('CallablaArray', Array, function(){ .. })
|
||||
// produces an Array that looks like a function but does not act like one...
|
||||
var a = Reflect.construct(Array, [], Function)
|
||||
|
||||
// creates a function that looks like an array...
|
||||
var b = Reflect.construct(Function, [], Array)
|
||||
```
|
||||
|
||||
This will produce an instance broken in a different way:
|
||||
So these will produce partially broken instances:
|
||||
```javascript
|
||||
var CallablaArray = object.Constructor('CallablaArray', Array, {
|
||||
var A = object.Constructor('A', Array, function(){ .. })
|
||||
|
||||
var B = object.Constructor('B', Array, {
|
||||
__call__: function(){ .. },
|
||||
})
|
||||
```
|
||||
|
||||
Some of this is due to how _object.js_ is currently implemented, this
|
||||
needs further investigation...
|
||||
Essentially this issue and the inability to implement it without
|
||||
emulation, shows the side-effects of two "features" in _JavaScript_:
|
||||
- lack of multiple inheritance
|
||||
- _hidden_ protocols/functionality (namely: calls, attribute access)
|
||||
|
||||
Still, this is worth some thought.
