I do not really think it's a bad solution, to check several

wondering if you have better ideas. Try to avoid modifying the

a really terrific idea.
void calc(double in1, double in2, double in3, double in4)
in {
foreach(const p; [&in1, &in2, &in3, &in4])
enforce(*p > 0);
}
body { /* ... */ }
Please imagine double is a type that I wanted to avoid copying,
just check by ref. Same question :p
