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);
}
