Either can gain even more optimized iterator methods by overriding the try_fold method added in 1.27; however, this will cause a pretty big bump in the minimum supported rust version (which appears to be 1.12 based on CI test configuration).

Oops! No it cannot, because it requires mentioning the unstable Try trait! 😛

I guess I'll leave this here though for once it actually can be done. (that time must be approaching not too long from now!)

We could use a build script to enable an internal cfg when Try is available.
