enummapset merge into containers

Not so long ago, it was suggested[1] that enummapset[2] might be a good candidate for merge into containers. Having found this package to be very useful in the past, I would find this quite nice. Would others find this a reasonable proposal? If so, what needs to be done to make this happen? Cheers, - Ben [1] http://blog.ezyang.com/2011/08/changes-to-intmap/comment-page-1/#comment-287...
