Suggestion - self.file alongside self.template that serves a single static file to a given URL.

It's really a synonym for self.template, it just explicitly doesn't do any preprocessing to the text. No real speed improvements, just clarity, being able to say that route X is completely static, no preprocessing.

IMHO this should automatically set the content-type as well.
Question: should this be restricted to the directory of the application to avoid accidentally service other files? If so, should there be an override for that safety?

[drforr]

I'd suggest adding an optional MIME-type variable on the call. Testing a file's magic can be unreliable and slow. Think for example of a 1MB UTF-8 with the only non-ASCII character being a copyright symbol at the end. This way the user can either override bad magic detection or set it for performance purposes.

I'd say by default it should use the same algorithm as the static file serving, (is that based on extension?) but the user can override it with an optional parameter as @drforr suggests.

This makes sense :)

[drforr]

Right. I wasn't suggesting avoiding the MIME-type check altogether, I was just suggesting a way to override the behavior. Usually checking magic is fast so it's not a problem, but I've worked with documents where it's unreliable, or sometimes you simply want to, say, upgrade text/ASCII to text/UTF-8 because it's the right thing to do.
