OK new release with the above patch

[meander/epsilon "0.0.626"]
meander/epsilon {:mvn/version "0.0.626"}

unsafe meander by using get instead of valAt sometimes is slower than safe meander

Yep

We can tweak that to be be very unsafe in that case. 🙂

I’m pretty sure the same is true of nth

In the case I described with Jimmy, we had used get and, in that case, the type checks were a part of the slow down.

I’m happy to add another flag for preserving .valAt and .nth.
