.rehash

[bearophile]

I think D builtins lack some very useful methods (member functions), like an index() for the arrays, a dup/deepdup for the associative arrays, and so on.
On the other hand I have tried to use the .rehash method few times, but most times its usage increases the total running time of my small program. So do you use the rehash method? If not enough people find it useful, then it may be removed, simplifying the API (freeing *brain* space for more important methods).
