[boost] [ptr_container] ptr_begin & family

Hello, If I'm understanding the Boost.PointerContainer docs, ptr_begin(), ptr_end() etc. are provided so that certain mutating std algorithms can be used on pointer containers. But wouldn't it be more convenient to provide a memfun like ptr_iterator make_ptr_iterator(iterator); for obtaining a ptr_iterator from a regular iterator? This way, one could easily use std algorithms not only with [ptr_begin(),ptr_end()), but also with any other range (for instance, those obtained from equal_range()). With this memfun, the ptr_begin() familiy would be kind of redundant. Just an idea... Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
