That might be clearer ;-)

If that's the case then the "Pointy subs" section of S06.pod should
probably be clarified a bit. It says that -> is a synonym for an
anonymous C<sub>, except for the lack of parens around the parameter
list, lack of a need for a preceeding comma when included in a list, and
the fact that it cannot be given traits. If there are more differences
they should probably be mentioned.

Ok, I see how it works now, but I still think the docs should be
clarified a bit.
