I'm heading down the C++ route, and tring to use id's/vnums more often.
this is especially true of things like the event systems around, eg the
player dies, the mob dies or something of that ilk and you're stuck with
a ptr to nowhere, with an id you just have to dereference it (and as I'm
using C++ it's fairly easy to do with a custom class or using map from

My general feeling is that C++ holds a lot of stuff these days,
especially as C++ compilers are getting better at optimizing templates.
Looking over some of the STL stuff I'm like that's just so nice, in
terms of you don't have to handle anything, you just insert an item and
that's it, no checking memory, allocating it etc.

I believe that Circlemud 4 is heading down a route of STL and C++,
although what's happening with it, it's all very secret ;)

like I said mostly to switch to using id's or vnums and avoid having too
many ptrs around the place, but certainly the crashes are a pain.
