I would like to add this as a method of string.Template, which I think amounts to changing "template" to "self" and putting it in the Template class in string.py rather than on its own. If the general idea is approved I would be happy to make a patch.

Make a patch regardless of whether you get any approval -- someone may later have a different opinion, and writing a patch records your work.

Also, on a related issue, does it make sense to scan the template string for invalid escape sequences in Template.init? For the applications I can imagine of string.Template, I would prefer to get an error upon creating the Template object rather than arbitrarily later when I try to .substitute with it.

No, create an is_valid() method at best.
