scalar grep defined($_) values %hashI think that should be: ...
It could be as you have written it, but I think moritz may have been considering the relative inexperience of the OPer by passing the parameter explicitly rather than implicitly.

Also, the code fragment was
    scalar grep defined($_), values %hash
(comma present after the defined($_) built-in call) in moritz's original reply (unless moritz has been updating replies without noting the fact – unlikely!).
