Summary:
Things like `float('inf')` are actually quite expensive.
```py
In [1]: import math
In [2]: %timeit -n 200 math.inf
49.3 ns ± 1.42 ns per loop (mean ± std. dev. of 7 runs, 200 loops each)
In [3]: %timeit -n 200 float('inf')
194 ns ± 39.1 ns per loop (mean ± std. dev. of 7 runs, 200 loops each)
```
