Maybe I've misunderstood your intent for this "Variant[string] info;" My
understanding is that, for example, you want to replace this:
----------------------------------------------------
class Exception {}
class FooException
{
string fooName;
int fooID;
bool didBarOccur;
this(string fooName, int fooID, bool didBarOccur)
{
this.fooName = fooName;
this.fooID= fooID;
this.didBarOccur= didBarOccur;
}
}
----------------------------------------------------
With this:
----------------------------------------------------
class Exception
{
Variant[string] info;
}
class FooException
{
string fooName;
int fooID;
bool didBarOccur;
this(string fooName, int fooID, bool didBarOccur)
{
this.fooName = fooName;
this.fooID= fooID;
this.didBarOccur= didBarOccur;
info["fooName"] = fooName;
info["fooID"] = fooID;
info["didBarOccur"] = didBarOccur;
}
}
----------------------------------------------------
If so, then I don't see any usefulness of "Variant[string] info" other than
to start treating exceptions like JS's abomination of an "object" (Or at
least AS2's objects anyway - not 100% certain how much of AS2 is taken from
JS). If not, then could you clarify what you meant?
In either case, I am interested to hear in more detail how you see
"Variant[string] info" being used to address i18n. I haven't really dealt
with a lot of i18n myself.
