hmm... it doesn't sound right at all. Forcing the developer to
remember to have to type ESCAPE=... for every TMPL_VAR is just not
right.
I personally forget to even use NAME=... and I just about never
quote the value either due to laziness.
The reality is that people are lazy/forgetful/efficient - the
general idea in life is to make life easier, not harder. I'd
suggest just to use the functionality as is. ie: set default_escape
to whatever the default is; when no escape is necessary, then the
developer will explicitly say so.

Please dont use "TEXT" to mean none - there is at least one filter
that has been posted on this list which is for 'text' documents.
ie: the filter is like the HTML filter, but also handles newlines &
carriage returns, etc. How about "NONE" or "NO" or "0" to mean 'no
escaping is necessary'.
Also, "NONE" (as described above) should be "THROW" - the term is
common in computer science, lets use it.
