That's what layers are supposed to do, fiddle with the text to make it

All depends on the use.  Color codes for instance are handled by the
third-party patches in a manner that relieves the output to something else.
The current socket code even takes care of buffering, formatting, snooping,
and prompts.  If you were doing lowlevel stuff, perhaps, but it's a whole
lot easier on yourself later if you abtract these things where they belong
instead of making every function call "intelligent."  Then later you have
to change every single "intelligent" function when you change behavior.

Because then every single little function in CircleMUD doesn't have to have
the logic to check for multiple messages.  To take your example of code in
the inventory list.  Now what do you do if you want the combat messages to
be stacked also?  Put the code there?  Or if you'd like people who spam
with 20 tells to be stacked? Though I think my code would require a delay,
except for slow connections, it is much more possible.

And you're going to be horribly duplicating code all over to match the

Which is the entire point behind C++, ye olde black box.

[1] - I should note that the patches are proof of concept mostly.  I never
did polish them up enough to be "pretty" but they were installed in my own
MUD and worked quite well, once I taught it various things it shouldn't
stack, like \r\n.
