I get what you mean btw? From my perspective though, the SG14 containers
aren't to replace custom-made solutions - they're for the many, many
programmers who don't care about nth-degree performance but are trying
to get code working, and end up re-implementing the wheel in very
suboptimal ways. For example, there's a lot of cases I get anecdotes
about where people need stable pointers so they end up using std::list
or std::map - neither of which are good for that purpose alone.

Colony fills that gap, and also the gap where people are implementing a
form of bucket array in suboptimal ways, for example, using a bool as
part of a struct to signify erasure.
