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.

Fix issue 8249 Spurious error message with templates and alias this

Lookup should be blocked only by errors in this template instance,
not by any global error.
