It is a pain, when coming from C++ which has the very impressive STL.  One 
of the things I absolutely hated is you cannot enumerate the elements in a 
hashtable and remove them as you enumerate (technically, D's builtin AA has 
this issue as well, but I have that ability in dcollections, and hopefully 
there will be a builtin range with that ability in the future *hint hint*). 
I have this really stupid piece of code where I enumerate through a lookup 
cache for finished threads, adding them to a list, then after enumerating 
through the hashtable, I have to remove them one at a time from the table by 
using the values I stored in the list, using a lookup each time to remove 
each element, when I could have removed them all without any extra penalty 
while traversing.
