What about values that aren't needed at compile time, but can be so optimized.

Running code at compile time in D is not an automatic optimization. Only code in certain constructs are ran at compile time, for example function calls in variable declarations or static if statements. Generally it's not something you even need to think about. This runs foo() at compile time:
int bar=foo();
int bar;
void main(){
bar=foo();
}
