A few questions for you to research:
- How old is C.
- How old is LPC.
- How old is Java.

Follow-up question:
- Which syntax do you think is more standard, tested, and tried?

And DGD will only be multi-threaded if you code it right.  You can
make multi-threaded support be pointless in -any- language, really.

The language used to implement DGD has absolutely nothing to do with
how it implements its persistent system.  If Dworkin had felt like it
he could've done the same thing in BASIC, I'm sure.

I've seen situations where the standard (32 bit wide) integer was too
small.  With recent DGD I'd probably have suggested to use the asn_*
kfuns to work around that, but it would still not be as smooth as just
being able to use +, -, * and / on integer values.

Read up on 'atomic', 'catch' and 'error'.
