[Hal Black:]

 &gt;One thing I'd really like to see, is have the modules made from VM code
 &gt;completely interchangable with modules made from native code.  That way,
 &gt;it would be a lot easier to replace VM code bit-by-bit with native code if
 &gt;you need to do so for performance purposes.  This would be especially nice
 &gt;if, say, the driver part was in C++, and there was a C++ to VM compiler.
 &gt;Then, you could swap stuff in and out of VM mode as desired for profiling,
 &gt;debugging, security, and so forth.

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@hits := player@hits - weapon@hits;

in my system, would have to be translated into something like:

    PutProperty(player, GetProperty(player, hits) -
			GetProperty(weapon, 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
good idea.
