Something like smart-quotes-mode, say?

In smart-quotes-mode, if you type this:

    Quoting 'like-this' should look nice.

this is the text you've entered:

    Quoting ‘like-this’ should look nice.

It'd be nice if Emacs had something like that for typing doc strings, along with 
the cleverer searches Drew mentioned.  However, I'm leery of making nifty 
features prerequisites for the most recently proposed patch, as that's a recipe 
for inaction.  Although the proposed patch's new functionality may be harder to 
use than we'd like, progress is made a step at a time and we can add more nifty 
features later.
