One a sidenote, is there some way for an object method to know if it

Is there some variable that is set that the function has access to
which is not set otherwise? Or can I use some kind of function
(caller) to inspect the call stack to figure it out? My object
contains both read and write methods, and I want to make sure the
write method calls are not callable from within a template, only from
native perl code. Any pointers would be most helpful.
If you have access to all the code, you could just set a global
variable right before processing the template and then check for that
in your function.
Hmmm... That is a reasonable suggestion. In my current setup this might
work.
But my next question is then, how can I go about to set this variable
automatically when $tt->process() is called? This way I don't have to
change the many occurences of $tt->process() in my code. Are there some
variable in the tt init code which could be set to a callback which is
automatically run whenever I execute $tt->process?
I was looking through the code, and the only thing I could think of that
could possible work is to use the [% CALL %] method, but then there is
also the question of how to prepend this chunk of code in front of all
the other templates without having to subclass Template...?
Suggestions?
