String Interpolation

I saw https://lampsvn.epfl.ch/trac/scala/changeset/25812/ being
mentioned on twitter, and I was wondering about it.

It seems interpolation is delimited by blocks starting with \{ and
ending with }, is that right?

There's a plugin providing string interpolation called Enhanced
Strings (http://jrudolph.github.com/scala-enhanced-strings/Overview.scala.html).
Was it considered when coming up with this change?
