 50% of the bugs in Unreal can be traced to these problems!


 Tim Sweeny isn't an amateur; he's responsible, at least in part, for one
 of the most commercially successful game engines ever.  I figure if even
 he has trouble with these things, it's worth trying to fix them.
 
 Note that D already solves #1 and #4, LDC could give us #3... that just
 leaves #2.  :D


 1 and 4 are pernicious, memory corrupting, hard to find problems. 2 is 
 easy to find, does not corrupt memory. It isn't even in the same 
 continent as 1 and 4 are.
 


The full cost to an enterprise of a catastrophic bug (which all 4 of these are
) in a released piece of software are almost certainly many orders of magnitude
larger than the cost of programmer time to find and fix it.
