I think 'protected' is the only remaining feature whose implementation is not "obvious". Otherwise, finishing support for all features is mostly a question of spending the time. Some performance tuning will be necessary too.

In theory, the frontend would be a good option because due to its design, it is quite easy to extend for incremental semantic analysis support. (It keeps track of all dependencies between nodes, all that is needed is to record those and to re-analyze dependent code as required.)

Nice initiative!

Certainly. :)

It took some time, but here is a version of dmd:

https://github.com/rainers/dmd/tree/tg_frontend

that can compile an updated frontend:

https://github.com/tgehr/d-compiler/pull/1

[The debug version of dmd hits 2 assertions during code generation, though (some real/ireal type mismatch, unlikely to make a lot of trouble in the release build).]

What needs to happen that this is merged into master? :)

Merged! Thank you for taking care of this.

I noticed it fails on a couple of tests from the testsuite. Will have to figure out, why...

There are a couple of issues involved, these will likely have to be split up to get a chance of getting merged.
