Oh no thanks ;-) I came here specially to see if there is some 
well known technique that I didn't hear about (I searched allot 
before posting here). If there is no such technique than it is 
just more interesting to explore !

Thanks all for your answers !

I thinks I'll continue exploring the lazy evaluation path and 
keep looking if there is a cleaner way to do it.
I'll specifically try to adapt lazy evaluation to ndsilces and 
see if I can have tangible results with benchmarks (by the way is 
there any good benchmarking lib like the #[bench] in rust that I 
can use ?) and study mir like it was suggested by Seb. I'll be 
very happy if I could contribute something useful for the D 
community :)
