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 of the form:

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
