If the range doesn't support copying, it shouldn't pretend to support it, and
algorithms relying on copy won't compile.

if the delegate had reference types in its scope (since presumably, they'd have
to be shallow
Is it in any way possible to copy a delegate? Take this program for example:
import std.stdio;
void main()
{
int a = 0;
int func()
{
return a++;
}
int delegate() b = &func;
int delegate() c = b;
writeln(b());
writeln(c());
writeln(b());
}
It will p
