- Regarding the Shootout I don't know how much useful it can be, because that site accepes only a really limited number of external libs, and generally accepts only a single sourcecode (maybe your code spits out D code that can be inserted in a single D sourcecode, but I don't know if the Shootout site accepts that).
- Regarding the compilation to D code, does it work only at compile time? Or does it call DMD at runtime?
- Regarding the generation of normal code, that later can be compiled, time ago I have found this, to use REs in the lwc compiler:

- There are TONS of open source RE engines around (the RE of TCL is very fast). I presume we can find one of them with a license fit for D, so we can just copy it into the std lib of D without writing yet another (slow, buggy, limited, etc) one.
