When application is remote from instantiation (for instance, when a template argument is supplied to a function), we get several problems. Given a line like "r = t % m", it is hard to verify that the code is correct. Should there be KeyError trapping? Can m be a tuple? Is t a %template, a safetemplate, or dollartemplate? Is the result a str or Unicode object? Should the decision of safe vs regular substitution be made at the point of instantiation or application?

All right, this moves me to +1, in the absence of any good arguments in favor of keeping the class-based system.
