Okay, I've been taking a look at this, and I'm facing a problem. When
I've scanned a string I want to actually replace all the {some_partial
foo:bar}'s with partial renderings.
I've been looking through the StringScanner documentation
(http://www.ruby-doc.org/core/classes/StringScanner.html), but it
doesn't seem to cover the topic of replacing matches instead of just
extracting it, if you know what I mean.
How can I replace a {some_partial foo:bar} match with a partial
rendering?
