Mason::Plugin::DollarDot - Allow $. as substitution for $self-> and in attribute names

       Jonathan Swartz <swartz@pobox.com>

       Will not interpolate as expected inside double quotes:

           "My name is $.name"   # nope

       instead you have to do

           "My name is " . $.name

       This plugin substitutes "$.identifier" for "$self->identifier" in all Perl code inside components, so
       that $. can be used when referring to attributes and calling methods. The actual regex is

           s/ \$\.([^\W\d]\w*) / \$self->$1 /gx;

       Mason::Plugin::DollarDot - Allow $. as substitution for $self-> and in attribute names

       In Mason 2, components have to write "$self->" a lot to refer to attributes that were simple scalars in
       Mason 1. This eases the transition pain.  $. was chosen because of its similar use in Perl 6.

       This plugin falls under the heading of gratuitous source filtering, which the author generally agrees is
       Evil. That said, this is a very limited filter, and seems unlikely to break any legitimate Perl syntax
       other than use of the $. special variable (input line number).
