Is there a usable alternative to Boost's bimap in C++0x?

I would like to avoid Boost, but fully embrace C++11. If necessary, a slimmed down version of Boost's bimap would work for me (I need a constant bimap to switch between enums and corresponding strings) throughout my program. The map will be compile-time constant, so perhaps even two manually maintained maps aren't the optimal solution.

Thanks!

UPDATE: I found this on The Code Project, but it seems licensing may be an issue: http://www.codeproject.com/KB/stl/bimap.aspx?fid=12042&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=151#xx0xx

I'm just looking for a clean and easy solution (one header/source file or little extra, as two mirrorred maps are equally fine in my case).

Short answer: no.

Long answer: nope.


It should be noted that C++14's support for transparent comparators eliminates the need for Boost.Bimap 90% of the time*: when you need to key off of any given property of an object (stored or computed), often a simple, bitwise-comparable unique identifier inherent to/present in the object anyway. With transparent comparators, you can compare an object to any possible value, discriminated only by type, as long as said value can be obtained/computed from an object without mutating it.

* a guesstimate, not a statistic
