Commit to not comparing NaN keys (#110)
Commit to not comparing NaN keys (#110)

Go 1.12 adds the ability to range over NaN keys.
However, it turns out that even with this functionality, there is still
no obvious way to compare the values. Thus, commit to behavior of just
panicking and letting obscure maps like this be handled by a custom Comparer.

Fixes #93
