since when does scalar context of a list result in a join???
It does? Which of your examples do you think supports this notion?
The scalar is applied to the list before the x-op can act. The parens are ignored...
I do not know what you mean by this.
Thats a bug or a feature?
From 'man perlop': 
       Binary "x" is the repetition operator.  In scalar context or if the
       left operand is not enclosed in parentheses, it returns a string
       consisting of the left operand repeated the number of times specified
       by the right operand.  In list context, if the left operand is enclosed
       in parentheses or is a list formed by "qw/STRING/", it repeats the
       list.  If the right operand is zero or negative, it returns an empty
       string or an empty list, depending on the context.
