I would point out that there are no plans to implement any kind of memoization 
in the language or compiler. Also, while it can help performance, it can also 
_harm_ performance. So having it controlled by the compiler is not necessarily 
a great idea anyway. It's really the sort of thing that should involve 
profiling on the part of the programmer.

If you want memoization, use std.functional.memoize.
