"...the dubious optimization of no interior pointers..."

this is the ONLY (i emphasise it!) way i were able to make my e-mail and 
irc clients to not leak memory, and keep using GC. on 32-bit systems false 
pointers *is* a problem, and NO_INTERIOR really helps.

turning NO_INTERIOR into something dog-slow (or noop) will make D unusable 
on 32-bit systems for anything more complex than helloworld and throwaway 
scripts. particularly, any app that should work for weeks or monthes 
without restart (yep, i want my mail client to Just Work, and i'm not 
rebooting my PC that often) will be *forced* to ditch GC.

while NO_INTERIOR requires some coding discipline, it is invaluable in IRL apps.
