+### String interpolator for XML literals
+
+We have wanted for a long time to deprecate XML literals in Scala and replace them by a string interpolator. That is, instead of
+
+    <body>
+      ...
+    </body>
+
+future Scala programs would use an interpolated string
+
+    xml"""
+      <body>
+        ...
+      </body>
+    """
+
+This project should turn the wish into reality by implementing the
+`xml` interpolator. The implementation should re-use most of the
+existing infrastructure for xml literals. It would probably be a good
+idea to re-package the existing XML parser in the Scala compiler, and
+to map interpolated strings to constructors from the existing
+`scala.xml` library. Some other aspects need to be re-thought. In
+particular name-space management should be handled by implicts
+instead of being hard-coded in the Scala typer.
+
+The project is a success if it can support essentially all legal XML
+expressions in Scala as interpolated strings. By contrast, support for
+XML patterns is optional: it would be nice if we could do it, but it's
+not required.
+
+This project is ideal for someone who knows XML basics, and is
+interested to learn enough about aspects of the compiler (either Scala 2.12
+or Dotty) to identify what can be re-used.
