Putting it at the stash level seems to be a mistake to me...you often want 
to manipulate the data and do a lot of stuff and not have to worry about 
filtering it until the last matter.  You're essentially dealing with the 
data at too early a place in the parser.

Since we're talking about being lazy here, I'd probably implement it as an 
option to auto filter interpolated variables.  So in this example:

  This is a [% foo %] with very many $bar.

foo would not be filtered, but $bar would be.  This seems to give you the 
right degree of balance between convenience and flexibility.

Does this make sense?

Mark.
