[via Digitalmars-d]

Rust is getting a mid level IR for speeding up compilation.

It has been mentioned that before that this would be worthwhile 
for D too.

It also would make it much easier for backends to keep up with 
the front end. The front end generating MIR, and the backends 
using it.

Another option would be to interface with Rust by generating Rust 
MIR from D, if that is possible.

What do you think?
