I've been working on code that works a lot like string.Template and in
the process, I stumbled on re.Scanner. I have two questions.
1) Is re.Scanner ever going to be official? Can I count on it being
in future versions of python? It's been there for a really long time,
so I assume so, but something that's undocumented seems that it could
be dropped easily.
2) Is there a reason that string.Template doesn't use re.Scanner? My
understanding of re.Scanner is that it is exactly what you want for
something like string.Template.
