Or be a bit more explicit about what you're doing, and put:
return;
at the end...
The reason for the behaviour causing the warning is that in the absence of
an explicit "return" statement, a perl sub returns the last evaluated
expression. Obviously, the calling function is checking to see whether
there is a returned value, and whingeing if it is the wrong type.
