Janet is ALMOST an incredible tool...but what I want is a very clear bifurcation between the standard library's stateful mutating procedures, and stateless value-returning functions. I ran into that wall hard trying to make something non-trivial.

It also turns out that the mix is due to the standard library leaning on raw C loop iterations underneath whenever it can. Which is great! But it confuses the library's interface paradigms.
