Seems like a lookup is not attempted if an error has previously occurred in the
module. This example comes from template9.d, and was based on bug 7580.
--------
void deliberateError() { int someError = "abc"; }

void fred()(int value) {}

struct YY
{
    int  val;
    @property int get()() { return val; }
    alias get this;
}

void test()
{
    YY y;
    fred(y);
}

bug.d(1): Error: cannot implicitly convert expression ("abc") of type string to
int
bug.d(3): Error: template junk.fred() cannot deduce template function from
argument types !()(YY)

The second error disappears if the first line is commented out.
