Joe Gottman pointed out:

No. It returns empty string. You could think of C<join> as being

    sub join (Str $sep, [EMAIL PROTECTED]) { reduce { $^a ~ $sep ~ $^b } "", 
@list }
   If this were the case, then
        join '~', 'a', 'b', 'c'
     would equal '~a~b~c' instead of 'a~b~c'

Good point. Thanks. Make that:

    sub join (Str $sep, [EMAIL PROTECTED]) {
        reduce { $^a ~ $sep ~ $^b } @list || ""

Presuming (of course) that my earlier plea that || should preserve context across both operands is granted. ;-)
