It is relatively incomplete and does not compile with official DMD 
releases that are newer than 2.060. This is because I used too much 
metaprogramming. Rainer had a patch for DMD 2.073.0, but it broke other 
projects.

The test suite should give some indication what it can do:

It has Turing complete templates and has relatively fast CTFE using a 
byte code interpreter, but is missing a lot of the bells and whistles.

Also, it is a frontend only so far, no backend code generator (other 
than for the CTFE byte code).
