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.
