After hacking around with some simple dynamic programming, it occurred to me that it should be possible to write a simple class template to handle memoization of functions. With the changes in C++0x that help solve the forwarding problem, writing a generic memoizer should be fairly straightforward. (Or so I thought!)
Comments and criticisms are welcome. If there's interest, I will - of course - work on a version that supports the current C++ standard.
The implementation of less in upgradable_tuple_inner doesn't look quite right. return get(as_ref) < rhs.get(rhs_as_ref) || tail.less(as_ref,rhs.tail,rhs_as_ref); Shouldn't this be return get(as_ref) < rhs.get(rhs_as_ref) || (!(rhs.get(rhs_as_ref) < get(as_ref)) && tail.less(as_ref,rhs.tail,rhs_as_ref)); Also, upgradable_tuple_inner::upgrade isn't exception safe. Fairly minor and maybe I shouldn't be worrying about them at this stage, but still... In Christ, Steven Watanabe
