I think you're getting confused about what the sigil applies to.  $foo or
${...} always represents a scalar, never a list.  In "$foo->bar", the $
sigil applies to the "$foo" part, and accurately indicates that it is
a scalar.  That the "bar" method can return a list doesn't invalidate
the consistency of the sigil's meaning.
