This is wrong D2 code (there is no foo):


void main() {
    enum int x = 1;
    pragma(msg, foo!x);
}


DMD 2.056head gives a partially wrong error message, that contains a "__error":

test.d(3): Error: template instance foo!(x) template 'foo' is not defined
__error

 __error


[Replying in the ng, because bugzilla is down]
The "__error" isn't part of the error message. It's coming from the 
pragma(msg): it's printing foo!x, and that's an error, so it prints 
"__error".
The real bug is that the pragma msg is still displayed, even when an 
error occurs while evaluating it. Maybe it should give an error

test.d(3): Error: template instance foo!(x) template 'foo' is not defined
test.d(3): Error: parameter for pragma(msg) must be a string
