Sorry if this has been asked before, but I am wondering what the use of std::vector::front() is.
Is there a reason to use e.g. myvector.front() rather than myvector[0] or myvector.at(0)?
Some of the generic algorithms that also work on lists use it.
This is an example of a general principle: if you provide accessors for all the semantics you support, not just the implementation you support, it is easier to write generically and therefore easier to reuse code.
