is that a bug? should i file a bug report?
---
import std.range;
struct A{
int x;
//bool opEquals(const A a) {return a.x==x;} //comiles when this
is used
//bool opEquals(const A a)const{return a.x==x;} //will not
compile
bool opEquals(A a)const{return a.x==x;} //will not compile
}
struct Range(S){
auto front(){return 0;}
auto popFront(){}
auto empty(){return false;}
}
void main(){
auto a=Range!A();
zip(a,a);
}

related question:
what is the "standard " signature for opEquals ?
is it:
bool opEquals(const ref A a)const
bool opEquals(A a)const
bool opEquals(A a)
?
