Re^3: hash count

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!).

(unless moritz has been updating replies without noting the fact – unlikely!). I did, mea culpa. (I sometimes do that when the node is still very new and there are no replies and it's a small change. But if it causes confusion, I try to clarify it).	[reply]
