Expose the CTFE interpter in Phobos?

[Peter Alexander]

CTFE isn't really an interpreter in the traditional sense. I believe it 
just uses the parsed source in its IR form, which is different from 
normal byte code interpreters (and also slower). I'm guessing here 
though, so I could be wrong.

Whether I'm right or wrong though, I don't see much use for this. As you 
said:

- CTFE is limited.
- You'd need nearly the whole D compiler, as well as the standard 
library and runtime.
- It would be slower than other scripting languages (unless given lots 
of attention).
- D wasn't made to be a scripting language.

The most important thing is simply that CTFE is a function evaluator. 
For scripting, that's pretty much useless. You need an entire virtual 
machine that you can call into, one that has state and can bind into 
your main application.

I think this would be a lot of work for little gain.
