:Is that in the MUD language, or the language used to implement the MUD?
:Neither of mine has a garbage collector. The implementation language is

:the use-counts of anything it points at decremented, etc.
Never really thought about this, but I DO have a GC for both... Yee! You
see, I wrote a reference counter (recursive references create a refset,
and external references are counted, so it is not prey to the usual bug
in reference counting schemes. I wrote it as a way to prevent memory
leaks. (I've already taken care of the pointer/array problem.) It never
struck me as that important, though... I can still use new and delete, and
do, though both have been overloaded, and as the ref counter tells me
whenever it has to clean anything up, and has not except for in the
testing process... as for the internal language... I admit it, I'm
coddling the builders! *shrug*
