With ruby 3.1.0 on my LXC box, this is the only problem reported as a failure with `make test-all`.

01:21 PM Ruby Feature #12075: some container#nonempty?

Boolean `size?` looks good to me. I vote for it.
My first choice was `nonempty?` because this is very common word in popular algorithm text books, e.g., Knuth, Cormen, Sedgewick, Tarjan, Aho, Hopcroft, etc.

01:41 AM Ruby Bug #17318: Raising float to the power of other issue

That depends on your purpose or background of the problem. In non-math situations, `power(a, b)` should not return any ordinary number for given `a`<0 where `power(a, b)` stands for "`a` to the power of `b`" over real, just identical to ... gotoken (Kentaro Goto)
