If the objective of the hook is to return a Boolean, return 1; or return 0;. I find the idea of sometimes returning 1 and in the case of "false" returning nothing a bad idea.

Yes, a "bare return" return;, will return "nothing" which can be interpreted as "undef" in the caller's code.

"return 0;" is crystal clear. I am returning a false value and I expect you as the caller to check this value. A simple "return;" is also used in the context where there is NO return value and I do not expect the caller to check it. I argue to make the code crystal clear. Geez if this code returns a Boolean, then there must some code somewhere like "return 1;", mirror that for the false value with "return 0;".
