I accidentally compiled some trivial D2 code with D1 and got a bad suggestion
from the compiler. Here is a trivial testcase:

---
import std.stdio;
void main() {
    writeln("bug");
}
---

t.d(3): Error: 'writeln' is not defined, perhaps you need to import std.stdio;
?
t.d(3): Error: function expected before (), not __error of type _error_

Both errors are really confusing. First, std.stdio is already imported (but D1
doesn't have writeln(), just writefln()). Then there is a crpyptic error about
things that are not even present in the file.
