The following program should print "free variable", but instead prints "parameter":
---
import std.stdio;
string _param_0 = "free variable";
void fun(string)
{
writeln(_param_0);
}
void main()
{
fun("parameter");
}
---

I'm not certain what we can do in this situation. Apart from maybe adding a second underscore; that way we will be covered by the spec. Is that what this bug report is asking for?

To be clear, I don't think that adding a special rule to make name resolution bypass the generated name is worth it.

Yes, adding a second underscore would fix this.
