I don't understand this argument. Of course the _result_ of the
evaluation is inserted into the template, but why is it useful to
evaluate the expression itself in the context of the template buffer? Is
it likely that one would be interested in some information only
available in the template buffer? To me it seems that the much more
likely case is the one of Rainer -- i.e. the need to access variable
bindings from the original buffer (buffer name, mode, other local
variables etc.).
