Nice work, I especially like that it is only a header file.

I have an idea, might be somethiing to add.
Instead of relying on the OTP version for some features.
Maybe add a macro like ‘OTP_SUPPORT_MAPS’ ?

Another we often define is for the changes in the dict() type, which became dict:dict() at some point.

In our rebar files we currently have definitions for this kind of defines.
Would be very convenient to have those at a more central place, and one that is consistent between projects.

Thank you for your library!
