Review Comment:
@mridulm I agree with your viewpoint. Currently, I have transformed the code
from checking `!refill()` to checking `refill()`, and adjusted the
corresponding handling logic (I have not yet updated the PR description). Do
you consider this to be acceptable? If not, I will close this PR.
