Damn, you are fast David :)
Thanks, that works great.
Yes this is rather cumbersome. I like the idea of implicit concatenation, and
that as one of the first things I tried but on the first element was being
used. And I agree on the whitespace unless you can come up with an operator
that says "anything inside of this is a literal but I honor attributes in [].
Kind of like the difference between "" and '' in perl say.
{{The road name is [st_name] and it is category [cat]}}
as opposed to
"The road name is " [st_name] " and it is category " [cat]
Either would be a vast improvement though.
