I'd like to see the rule for template template argument compatibility relaxed (e.g. such that std::vector<T,A=allocator>
and myclass<T> would both be compatible with a template template parameter declared as template <class>). The current
rule appears to have been adopted to better meet with users expectations (as compared to function pointer
compatibility). The not-infrequent threads on c.l.c++.m about this subject suggest that it did just the opposite:
institutionalized behavior which is counter to expectations and unnecessarily limiting.
