Would it not be possible to have an implementation of TemplateProvider that 
used the name of the template as the contents of the template itself?

This would let you say:-

#include as template "<p>Hello, $name</p>"

or

#include as template "$templateSource"

Of course, this would rather cripple your normal template loading, so there 
could be a switch which looked for a given header such as:-

#include as template "evaluate:$templateSource"

and if it didn't start with "evaluate:" then it would just delegate the 
request to the default template loader.

If this fixed your problem then it would be relatively easy to implement...
