Ah, I think I've got it.  Per "man perlfunc":

           "our" has the same scoping rules as "my" or "state", meaning that
           it is only valid within a lexical scope.  Unlike "my" and "state",
           which both declare new (lexical) variables, "our" only creates an
           alias to an existing variable: a package variable of the same name.

Since there's not actually any such package variable, the net effect is
that the first argument of open() is an undeclared name.  I can more or
less see why perl might treat that the same as a bareword, though I
definitely agree that this error message is more confusing than helpful.
