would that be to implement? eg:

struct Status{bool ok; string msg;}
Status status = __traits(compilesReportError, {string b=10;})
assert(!status.ok);
assert(status.msg==`main.d(15) Error: cannot implicitly convert
expression 10 of type int to string`);
```
Probably not very hard. Would make for some nice diagnostics,but
very flakey tests. Compiler errors are frequently changed.
