Hi there,
I have a hash table where I want to do some action for each value in
the hash table.
Among other possibilities I could do like this:
map { some_action($_) } values %ht;
where let us say:
sub some_action {
...
return;
}
I like it because it is really short.
Questions:
1. Is there another perhaps better one liner to do it?
You can do either of these:
map some_action($_), values %ht;
some_action($_) for values %ht;
