[stringtemplate-interest] Anonymous template inside another anonymous template

[Terence Parr]

Howdy.  Can you explain more at the high level of what you're trying to do?  are you passing down a recursion chain a bigger and bigger arg?

I'm finding now that when I want recursion, i'm walking the model with the template; less good.  I recurse or traverse my model and build a tree of embedded templates rather than having the template invoke itself.
