oops the online editor saved a mix of an old iteration and a new 
one ... (probably my fault)

import std.stdio;

float test(float x)
{
    float r = -1;
        static foreach(i; 0 .. 100)
        {
            static if (__traits(compiles, Check)) {} else {
                static if (i == 10)
                    enum Check = 1;
                r = i * x;
            }
        }

    return r;
}

void main() {
        float ret = test(4.2);
    writefln("ret = %s", ret);
}
