Even better, don't use vector<const char*>. What o you need that for? [snip]

Here's a real motivating example where I want to use vector<const char*>. I have a large file containing null-terminated strings which I memory map. After opening the file, I construct some sort of index of those strings in a sorted vector. Then I search for things using std::equal_range, std::lower_bound, or similar.

That's a good example, I grant you.

I actually have a helper class for this called cstrptr which is a typedef for the template class

basic_cstrptr<char>. It is a "dumb" wrapper around const char * that provides some std::string

Also, something like iterator_range<const char*> might be somewhat more handy to store in the vector.

Perhaps in the generic case, but as I said, my class is for magic text found in programs and you practically never need to run generic algorithm against lists of magic text. The value in my class is that it is basically the same size as a pointer to char and has a near nop constructor. But my class might be too specific for boost based on the lack of any reaction to the concept. It is just a little fluff class. Joe
