Just a few ideas, I think there's a few declarative features I'd like
to see added:
- I'd *really* like to see some declarative syntax for setting
{DontEnum} flag on properties in object initialisers.
- A declarative way to set catch-alls.
- A declarative way to set the [[Call]] property.
- And maybe declarative way to set the [[Prototype]] property. (This
would of course be const.)
var
a={
dontenum toString: function()'[object customObj]'
},
b={
[[Prototype]]: a,
[[Call]]: function()...,
get *: function(propname)...,
set *: function(propname, value)...,
...
};
The brackets for syntax would from what I can tell work here, since
they are syntax errors in ES3. Or using some double keyword syntax I
guess.
