Review comment:
Nit: thanks for removing the unneeded initializer. Might as well move
the type into the `for` loop:
```
for (int id =...
```

Review comment:
I wonder if the tests should move to a file that is a bit more
descriptive? Do we have tests for string functions? Else, future folks won't
know that the code came from a "bug fix" and to look in this file.
Also, should we have tests for all the functions that were fixed? Presumably
those tests don't exist because otherwise we would have found the bugs sooner.
