--- Comment #8 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-04-12 09:33:14 UTC --- Uhm, short term, I like even better just not using _Select1st *at all*, have an implementation detail in the hashtable header itself not deriving from unary_function. Isn't that a bit redundant but cleaner?
