It doesn't have to be implicit though. A common pattern is to lob in a  
literal 'scalar' to make it explicit e.g. $count = scalar @things;

I'm not sure it's particularly readable, and the useless invocation of  
scalar is possibly not optimal, but it unambiguously indicates that  
there's some kind of transforming operation in there.
