umm... why?  What benefit does this give you?  What kind of output are =
you expecting from the TMPL_VAR?

... its not clear how this requirement would be all that useful... or =
would even make sense in the context of "seperation of code and =
presentation" that H::T provides...

Using H::T::E sounds like the best solution...
