Rhesa Rozendaal continues to make and release improvements to HTML::Template::Plugin::Dot. Recently he got support for TMPL_LOOP tags work as well.
Michael Peters soon added support to CGI::Application::Plugin::AnyTemplate.
Jason Crome released CGI::Application::Plugin::HTDot, which simply replaces CGI::Application's load_tmpl() with one that supports the dot notation.
Private, I received an inquiry if this will work with HTML::Template::Expr. That's not something I have looked to, but am interested to support.
For the next act, Rhesa is looking to some performance benchmarks to access how this solution compares to others.
