I think it's really important to have such features available in the
development stack tools. It makes it much easier to integrate applications
into IDE's, so that's great.

If you apply for that it would be great if you came up with something that
is really useful. Right now it's working pretty well with the system we have
in kdevelop (although it could be improved, of course). So you will have a
good application if you can find a good added value to the current state.

Here you can check what such code looks like right now:
