Warning: I'm pretty pro-STL so take what I say with the appropriate
bias. :-)

The fact that it's generic is why I like it -- I hate having to write
the same algorithms over and over again just because I'm using them on
different data types (e.g., removing an item from a list). With STL
this is all pretty easy.

This is a minor problem IMHO, and certainly no worse than our current
system where you already risk crashing if you remove something from a
list in the middle of iterating through it. Bugs just like this crop
up over and over again over the years. A new CircleMUD written
from scratch (which is the way I'd really rather go) might, say,
flag something as needing to be removed from a list, with garbage
collection at the end.

Any implementation of map that uses linked lists is severely broken -
most use something very hard-core and fast like red-black trees.
(That's why the element you use to index it needs the < operator
defined in order to use it in a map<>).
