So you're saying the following is unclear, even to someone who knows but the very basics?
if (!@clients) { ... } for (0..$#clients) { ... } if (!keys(%tasks)) { ... }

I would say those are rather readable, even without the "..." populated. They should be crystal clear with the "..." populated. Whether the parts are meaningful in isolation is not very interesting.

For instance, it isn't at all obvious that scalar keys %$some_hash returns the number of hash elements in constant time.

That's got nothing to do with readability. You wouldn't say hash.num_keys is unreadable, yet we know nothing of the efficiency of num_keys.
