I'm thinking that we want a method like

emitTemplateBoundaryDebugStrings("<!-- start $name$", "-->");

where the args are templates and may reference name for the  
template...what else would be useful?  The stack context like <!--  
[outputfile class method statement ... --> ?

[For those just tuning in from ST list: we want to print out text at  
start/stop of each template dumped out so we can figure out where  
text is coming from.]
