Sorry for the typo. This is the problem
auto arithmetic(T, V, U)(T a, V b, U op){
return mixin("a"~op~"b");
}//call like this arithmetic(1.5,2.5,"+");Compiler says the variable op is not reach at compile time. So how can the varible a and b be reach at compile time and op is not reach. I will appreciate any help. I have also use a static if but the same complain. Just a newbie in D
