Two reasons come to mind. First, you can't really manipulate the values (to untaint them) as param() isn't an lvalue. Second, the context is unambiguously scalar in this case. In a print statement, it may be unintentionally list.

Oh, and a third might be for the efficiency of not calling a method repeatedly.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
