# Rationale for this change
Speedup for (common) case of non-null indices array:
```
Benchmarking take bool 512: Collecting 100 samples in estimated 5.0003 s
(6.8M i
take bool 512 time: [733.01 ns 733.90 ns 735.34 ns]
change: [-76.500% -76.428% -76.358%] (p = 0.00 <
0.05)
Performance has improved.
Found 3 outliers among 100 measurements (3.00%)
3 (3.00%) high severe
