Hi all, I'm working on a very large associative array implementation that stores most of the data on disk, and I need to allocate a number of cache areas for keeping "hot" disk pages in RAM. Is there a way to allocate GC memory blocks in D that are guaranteed to fall on OS page boundaries? Or shou

H. S. Teoh: On the other hand, AA.byKey() will return a *lazy* sequence of keys (i.e., it won't actually walk the AA unless you want it to), so doing this ought to be O(1): auto mykey = myarray.byKey().front; myarray.remove(mykey); In general the associative array table can

In theory, it should be possible to do a "popFront" equivalent for a hash that has O(1) average complexity, so long as you don't care about order. I.e., "give me any key from the hash, I don't care which one, and then delete it from the hash". Is that correct? If it is correct, is there any
