As I mentioned in an earlier note, problems arise more from run-time
library or support environment than from strict language issues. In this
particular instance, please note that C++ is a very large language - building
a compiler for it is man-years worth of work. There are some available
parsers out there, but then the problem of licensing can come up.
An in-MUD language will typically have language elements that are added
to make in-MUD programming easier. Those won't exist in external languages,
and so that stuff would have to be translated into function calls,
possibly quite a lot of ugly ones. As an example, the statement:
player at hits := player at hits - weapon at hits;
in my system, would have to be translated into something like:
PutProperty(player, GetProperty(player, hits) -
assuming you have simple values usable as database identififers.
Keeping the in-MUD language(s) for higher-level world/quest/NPC stuff and
the native compiled language(s) for lower-level things is probably a
