I think Leonardo might have a point here. Built-in support for
Singletons could be a nice feature, without the use of static
functions, would be nice. I wouldn't use the 'new' keyword however. I
think something along the lines of existing, or ref
$ref = existing TEST; // which would return an existing instance of
TEST, if one exists, and a new one if it doesn't. ( pretty much like
the singleton code, except no need for singleton code)
I don't think it's anything important, and there are more pressing
matters, to be worked on, I'm sure, but if someone created the code,
and it was secure / bug-free / compliant-with-coding-standards / etc,
I can't see why it couldn't(or shouldn't) be included. When all's said
and done though, it's still just syntactic sugar. It all depends on
how sweet the devs consider it.
