I think my thoughts still apply to the module. There could be valid
warnings else where in the code which the developer would miss if the
warnings are suppressed for the entire file. If the code generating the
warning is documented (with a comment) as to why it can be ignored, that's
acceptable for now. Warnings are a good thing since they make you think
about why your code is generating the warning.
